unexpand: correct behavior for --first-only --tabs=4

2020-06-09T13:40:49+00:00

Prior to the patch, both -f and --first-only are in all cases either
no-op or ignored.
Without --tabs, --first-only is the default so specifying it is a no-op.
With --tabs, --all is implied, and --first-only is intended to reset this.

grep: add proper support for pattern_list

2020-04-29T22:20:18+00:00

From POSIX.1-2008:

	The pattern_list's value shall consist of one or more patterns
	separated by  characters;

As such, given patterns need to be split at newline characters. Without
doing so, busybox grep will interpret the newline as part of the pattern
which is not in accordance with POSIX.

grep: Fix -f FILE when FILE is empty and -x provided

2020-04-29T14:01:42+00:00

Grep currently special-cased empty pattern file to be the same as
pattern file with one empty line (empty pattern). That does mirror how
GNU grep behaves, except when -x is provided. In that case .* pattern
needs to be used instead.

xargs: restore correct behaviour of -n option

2020-04-29T13:53:51+00:00

Since commit 1ff7002b1 (xargs: fix handling of quoted arguments, closes
11441) the -n option hasn't worked properly:

   $ echo 1 2 3 | xargs -n 1 echo
   1
   2

   3

   $

Because state is now remembered between calls to process_stdin() it's
necessary to update the state before any premature return.

xargs: fix handling of quoted arguments, closes 11441

2020-01-29T13:39:13+00:00

As reported in bug 11441 when presented with a large number of quoted
arguments xargs can return 'argument line too long':

   seq 10000 29999 | sed -e 's/^/"/' -e 's/$/"/' | busybox xargs echo

This happens because the variant of process_stdin() which handles quoted
arguments doesn't preserve state between calls.  If the allowed number
of characters is exceeded part way through a quoted argument the next
call to process_stdin() incorrectly treats the terminating quote as a
starting quote, thus quoting all of the argument separators.
