Subject: [PATCH] gitk: Handle 'copy from' and 'copy to' in diff headers.
X-Git-Tag: v1.5.3-rc6~1^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d1cb298b0b74972cc27c789e4c9ce6f324f25113;p=git.git

[PATCH] gitk: Handle 'copy from' and 'copy to' in diff headers.

If a commit contained a copy operation, the file name was not correctly
determined, and the corresponding part of the patch could not be
navigated to from the list of files.
