new coreutils snapshot

[Jim Meyering]

Since the last snapshot, not much has changed in coreutils proper,
but some of the recent changes in gnulib that may have an effect.

2007-04-25  Jim Meyering  <address@hidden>

        * src/du.c (usage): Clarify description of --dereference-args (-D).
        Prompted by a report from Justin Pryzby.

        * bootstrap.conf (gnulib_modules): Add fseeko and ftello.
        (gnulib_modules): Add autobuild.

        * THANKS: Add Andreas Frische.
        * NEWS: Mention today's ls --color fix.
        * tests/ls-2/tests (sl-dangle): Add a test for today's fix.

        ls --color once again colors dangling symlinks correctly
        * src/ls.c (gobble_file): Much like the 2007-04-07 fix,
        add a term to the expression that decides whether we need
        stat and/or lstat calls.  Reported by Andreas Frische.
