Subject: [PATCH] gitk: Fix nextfile() and add prevfile()
X-Git-Url: https://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=67c22874cf82edae9b5c5f0a47c432d08d7ad426;p=gitk

[PATCH] gitk: Fix nextfile() and add prevfile()

The current nextfile() jumps to last hunk, but I think this is not
intention, probably, it's forgetting to add "break;". And this
patch also adds prevfile(), it jumps to previous hunk.
