Running an applet with '--help' as its only argument is treated
as a special case. If additional arguments follow '--help' the
behaviour is inconsistent:
- applets which call single_argv() print help and do nothing else;
- applets which call getopt() report "unrecognized option '--help'"
and print help anyway;
- expr says "expr: syntax error" and doesn't print help;
- printenv silently ignores '--help', prints any other variables
and doesn't print help;
- realpath says "--help: No such file or directory", prints the path
of any other files and doesn't print help.
If the first argument is '--help' ignore any other arguments and print
help. This is more consistent and most likely what the user wanted.
See also commit 6bdfbc4cb (libbb: fix '--help' handling in
FEATURE_SH_NOFORK=y).

The idx variable points to a value in the stack string (as managed
by STPUTC). STPUTC may resize this stack string via realloc(3). If
this happens, the idx pointer needs to be updated. Otherwise,
dereferencing idx may result in a use-after free.

The line editing code and ash disagree when the current directory
is changed to a symbolic link:
~ $ mkdir real
~ $ ln -s real link
~ $ cd link
~/real $ pwd
/home/rmyf36/link
Note the prompt says we're in ~/real. Bash does:
[rmy@random ~]$ cd link
[rmy@random link]$ pwd
/home/rmyf36/link
Ash uses the name supplied by the user while the line editing code
calls getcwd(3). The discrepancy can be avoided by fetching the
value of PWD from ash.
Hush calls getcwd(3) when the directory is changed
so there's no disagreement with the line editing code.
There is no standard how shells should handle cd'ing into
symlinks.

When the 'cc' command is invoked with autoindent enabled it
should use the indent of the first line being changed.
The size of the indent has to be established before char_insert()
is called as the lines being changed are deleted. Introduce a
new global variable, newindent, to handle this. The indentcol
global is now effectively a static variable in char_insert().

Suppose autoindent is enabled and we have a line with an initial
tab where we want to split the words onto separate lines:
split the words
One way to do this is with the sequence 'f r<CR>;r<CR>', but in
BusyBox vi the result is:
split
he
words
This is a regression introduced by commit 9659a8db1 (vi: remove
autoindent from otherwise empty lines). The amount of indentation
is being recorded when the 'r' command inserts a newline but
isn't subsequently reset. A fix is to only record the indent
when in insert or replace mode. Proper handling of the 'o' and
'O' commands then requires them to switch to insert mode before
calling char_insert() to insert a newline.

ash and hush correctly use the value of HOME for tilde expansion.
However the line editing code in libbb obtains the user's home
directory by calling getpwuid(). Thus tildes in tab completion
and prompts may be interpreted differently than in tilde expansion.
When the line editing code is invoked from a shell make it use the
shell's interpretation of tilde. This is similar to how GNU readline
and bash collaborate.

The functions bb_perror_nomsg() and bb_perror_nomsg_and_die() are
used to print error messages where no specific information is
available. For example:
$ busybox mktemp -p /
mktemp: (null): Permission denied
mktemp(3) doesn't tell us the name of the file it tried to create.
However, printing '(null)' is a regression introduced by commit
6937487be (libbb: reduce the overhead of single parameter bb_error_msg()
calls). Restore the previous behaviour by reverting the changes to
the two functions mentioned:
$ busybox mktemp -p /
mktemp: Permission denied
