The same stored search pattern applies to both search ('/') and
search/replace (':s') operations.
A search/replace operation with an empty "find" string (':s//abc/')
should use the last stored search pattern, if available, and issue an
error message if there is none.
If the "find" string is not empty it should replace the stored search
pattern.

With FEATURE_VI_REGEX_SEARCH enabled backward searches don't work.
This is problematic on distros that enable regexes, such as Tiny
Core Linux and Fedora.
When calling GNU re_search() with a negative range parameter
(indicating a backward search) the start offset must be set to
the end of the area being searched.
The return value of re_search() is the offset of the matched pattern
from the start of the area being searched. For a successful search
(positive return value) char_search() can return the pointer to
the start of the area plus the offset.
FEATURE_VI_REGEX_SEARCH isn't enabled by default but when it is:

If the motion command used to define the range of a change, yank or
delete fails the whole command should be rejected. BusyBox vi already
handled failed searches in these circumstances. Add some more cases:
- non-existent mark: d'x
- movement beyond end of file: c99999+ or 99999<<
This is implemented using a global variable which is set when a command
error is detected. Unlike the case of motion within a line it's
insufficient to check that the motion command doesn't move the cursor:
this fails to process 'LyL' correctly, for example, as the second 'L'
doesn't move the cursor.

In traditional vi and vim line motion commands ('+'/'-'/'j'/'k')
fail if the movement would exceed the bounds of the file. BusyBox vi
allowed such commands to succeed, leaving the cursor on the first or
last character of the file.
Make BusyBox vi work like vi/vim.
For the 'G'/'H'/'L' commands traditional vi treats an out of bounds
result as an error, vim doesn't. BusyBox vi behaves like vim, both

Lines that have no content apart from automatic indentation should
be treated as empty when the user hits return or ESC.
The implementation uses the global variable 'indentcol'. Usually
this is zero. It can also be -1 to indicate an 'O' (open above)
command, replacing the overloading of the tabstop option bit.
A value greater than zero indicates that the current line has
been autoindented to the given column (or that the autoindent has
been adjusted with ctrl-D). Any other change to the line resets
'indentcol' to zero.
Replace strspn() with ident_len(). The latter handles the unlikely
case that it's called on the last line of a file which doesn't have
a terminating newline.

The 'y' command to yank text should leave the cursor at the start
of the range. This mostly works correctly in BusyBox vi but not
for whole-line yanks with backward motion, e.g. '2yk' to yank two
lines backwards. In this case the cursor is left at the end of the
range.
Fix this by returning the actual range from find_range(). Cursor
positioning following whole-line deletion is inconsistent between
vim and traditional vi. For BusyBox vi chose the option that uses
least code without being exactly compatible with either.
Also, find_range() preserved the value of 'dot', the current cursor
position. Since this isn't used by either caller of find_range()
we can save a few bytes by not bothering.

- If addresses are separated by a ';' instead of a ',' the current
line is updated to the left address. This may be useful when a

Line addresses in colon commands can be defined using an expression
that includes '+' or '-' operators. The implementation follows
traditional vi:
- The first term in the expression defines an address. It can be
an absolute line number, '.', '$', a search or a marker.
- The second and subsequent terms must be non-negative integers.
- If the first term is missing '.' is assumed. If the operator is
missing addition is assumed. If the final term in missing an
offset of 1 is assumed.
Thus the following are valid addresses:
.+1 .+ + .1
.-1 .- -
The following are not valid (though they are in vim):

Vi places the cursor on the last column of a tab character whereas
BusyBox vi puts it on the first. This is disconcerting for
experienced vi users and makes it impossible to distinguish
visually between an empty line and one containing just a tab.
It wasn't always this way. Prior to commit e3cbfb91d (vi: introduce
FEATURE_VI_8BIT) BusyBox vi also put the cursor on the last column.
However there were problems with cursor positioning when text was
inserted before a tab. Commit eaabf0675 (vi: multiple fixes by
Natanael Copa) includes a partial attempt to fix this. (The code is
still present but it's never executed. Clever compilers optimise it
away.)
Revert the changes of commit e3cbfb91d and fix the insert problem
for all tabs, not just the first.

Traditional vi is mostly silent about the results of yank, delete,
change, undo or substitution commands. Vim reports some details
about undo and substitution. BusyBox vi is positively verbose in
comparison.
Make some improvements to BusyBox vi:
- Add vim-like reporting of changes caused by substitutions, of
the form '64 substitutions on 53 lines'. This replaces a fairly
useless report of the result of the last change made.
- Ensure that the report about put operations correctly reflects the
newly introduced repetition count.
- Commit 25d2592640 tried to limit status updates for delete and
yank operations by detecting whether the register had changed.
This didn't always work because the previously allocated memory
could be reused for the new register contents. Fix this by
delaying freeing the old register until after the new one has
been allocated.
- Add a configuration option to control verbose status reporting.
This is on by default. Turning it off make BusyBox vi as taciturn
as traditional vi and saves 435 bytes.
