Subject: git-rm: honor -n flag.
X-Git-Tag: v1.4.0~7
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7612a1efdb0c0806b43db10ce784707aae874340;p=git.git

git-rm: honor -n flag.

Even when invoked with -n flag, git-rm removed the matching
paths anyway.  Also includes the missing check spotted by
SungHyun Nam, which caused it to segfault.  Now we refuse to run
without any paths.
