* gl/lib/mbsalign.c (rpl_wcswidth): Remove this in favor
of the equivalent wcswidth replacement in gnulib.
* bootstrap.conf: Depend on the wcswidth module.
Suggested by Bruno Haible.
* gl/lib/mbsalign.c: Include <stdint.h> for SIZE_MAX.
Use SIZE_MAX rather than (size_t) -1, to avoid warning for
"size_t x = -1" on Solaris 10 cc.
* gl/modules/mbsalign (Depends-on): Add stdint.
This module may be moved to gnulib at some stage,
so keep it C89 compatible.
* gl/lib/mbsalign.c (mbsalign): Declare variables at start of scope
(ambsalign): Likewise
* gl/lib/mbsalign.h: Remove trailing comma from enum
Reported by Andrei Suhan
* gl/lib/mbsalign.c (mbsalign): Ensure the temporary destination buffer
is big enough, as it may need to be bigger than the source buffer
in the presence of single byte non printable chars.
* gl/tests/test-mbsalign.c (main): Add a test to trigger the issue.
* gl/lib/mbsalign.c (mbsalign): Support the MBA_UNIBYTE_FALLBACK
flag which reverts to unibyte mode if one can't allocate memory
or if there are invalid multibyte characters present.
Note memory is no longer dynamically allocated in unibyte mode so
one can assume that mbsalign() will not return an error if this
flag is present. Don't calculate twice, the number of spaces,
when centering. Suppress a signed/unsigned comparison warning.
(ambsalign): A new wrapper function to dynamically allocate
the minimum memory required to hold the aligned string.
* gl/lib/mbsalign.h: Add the MBA_UNIBYTE_FALLBACK flag and
also document others that may be implemented in future.
(ambsalign): A prototype for the new wrapper.
* gl/tests/test-mbsalign.c (main): New test program.
* gl/modules/mbsalign-tests: A new index to reference the tests.
* .x-sc_program_name: Exclude test-mbsalign.c from this check.
* gl/lib/mbsalign.c (mbsalign): Mark unused parameter.
* bootstrap.conf (gnulib_modules): Remove obsolete
rename-dest-slash.
* gnulib-tests/Makefile.am (AM_CFLAGS): Reduce set of warnings for
gnulib tests.
* gl/modules/rename-tests.diff (Makefile.am): New file, to add
LIBINTL to LDADD, since we avoid canonicalize-lgpl module.
* gl/lib/regcomp.c.diff (regerror, calc_next)
(build_collating_symbol, parse_bracket_element, build_equiv_class)
(free_tree): Mark unused parameters.
* gl/lib/regex_internal.h.diff (re_string_elem_size_at): New file,
to mark unused parameters.
* gl/lib/printf-args.c.diff (PRINTF_FETCHARGS): New file, to avoid
type mismatch.
* gl/lib/vasnprintf.c (VASNPRINTF): New file, to avoid shadowing
local variable name.
* .gitignore: Ignore temporary build artifacts.
Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR
locale has recently changed to use the official but variable width
abbreviated month names. Other glibc locales also have variable widths.

* NEWS: Mention the fix
* gl/lib/mbsalign.c: A new module to align and truncate a
string in a specified number of screen cells, while handling
multi-byte characters appropriately.
* gl/lib/mbsalign.h: Ditto
* gl/modules/mbsalign: Ditto
* bootstrap.conf: Reference the new module
* src/ls.c (abmon_init): New function, precompute the abbreviated
months aligned left in a minimum width column <= 5 screen cells.
(align_nstrftime): New function, replace the first %b in the
format specification to strftime with the precomputed month string.
Note using the cached month strings speeds up `ls -lU` by around 17%
on glibc-2.7-2 on linux at least. Also if we implement this function
using heap storage rather than automatic storage, and use snprintf
instead of strcpy, ls will slow down by 2% and 1% respectively
(i.e. a net gain of 14% rather than 17%).
* tests/ls/abmon-align: A new test to test ls alignment for
various formats and locales
* tests/Makefile.am: Reference the new test
