51358757c7 vi: fix backward search with GNU regex
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:

9c291f2cc0 taskset: fix for PID longer than 12 chars
Should we validate that PID is a number for "taskset -ap PID"?
We don't actually need it, and pathological input like
"../../DIR_WITH_LOTS_OF_PIDS" can only cause "taskset"ing
of many pids. Which is something user can do anyway.

038d400709 vi: reject change command when motion fails
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.

ac04eb3657 vi: up/down motion beyond end of file should fail
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
before and after this patch.

f1d21b7434 vi: keep autoindent if line isn't empty
When ESC is entered to leave insert mode any autoindent should only
be removed if there's no content beyond the indent.  This may be the
case if a line has been split by entering insert mode and then
entering a CR.

Add a check to ensure there's only a newline after the indent.

f7ed0e8ae0 vi: ':r' should insert text after current line
When no line number is specified ':read' should place the inserted
text after the current line, not before.

This used to be correct but was broken when commit 0c42a6b07
(vi: fix empty line range regression) revealed a bug in commit
7a8ceb4eb (vi: changes to line addresses for colon commands).
