Subject: Fix git-update-index to work with relative pathnames.
X-Git-Tag: v1.5.0-rc3~9
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=9ebe6cf953123ce904fe6930991694e3a3c79c17;p=git.git

Fix git-update-index to work with relative pathnames.

In particular, it fixes the following (typical for cygwin) problem:

    $ git-update-index --chmod=-x ../wrapper/Jamfile
    fatal: git-update-index: cannot chmod -x '../wrapper/Jamfile'
