While "rm ''" would properly fail, "rm F1 '' F2" would fail
to remove F1 and F2, due to the empty string argument.
This bug was introduced on 2009-07-12, via commit
4f73ecaf,
"rm: rewrite to use fts".
* gnulib: Update to latest, for fixed fts.c.
* NEWS (Bug fixes): Describe it.
* tests/rm/empty-name: Adjust for changed diagnostic.
(mk_file): Define, copied from misc/ls-misc.
(empty-name-2): New test, for today's fix.
* lib/xfts.c (xfts_open): Reflect the change in fts_open, now that
it no longer fails immediately when one argument is the empty string.
Assert that the bit flags were not the cause of failure.
* po/POTFILES.in: Remove xfts.c.
* THANKS: Update.
Reported by Ladislav Hagara.
* Noteworthy changes in release ?.? (????-??-??) [?]
+** Bug fixes
+
+ rm once again handles zero-length arguments properly.
+ The rewrite to make rm use fts introduced a regression whereby
+ a command like "rm a '' b" would fail to remove "a" and "b", due to
+ the presence of the empty string argument.
+ [bug introduced in coreutils-8.0]
+
* Noteworthy changes in release 8.1 (2009-11-18) [stable]
