Subject: [PATCH] When copying or renaming, keep the mode, please
X-Git-Tag: v0.99.5~16^2~5
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=35cc4bcd10862db190df9685b7ad221f2a25404f;p=git.git

[PATCH] When copying or renaming, keep the mode, please

Without this patch, git-apply does not retain the mode when renaming or
copying files.

[jc: Good catch, Johannes.  I added a test case to demonstrate the
breackage in the original.]
