From: Junio C Hamano Date: Mon, 6 Feb 2006 00:08:01 +0000 (-0800) Subject: git-commit: finishing touches. X-Git-Tag: v1.2.0~41 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=5a798fb57f788692467b1a11416dd5ebff0d31ae;p=git.git git-commit: finishing touches. Introduce --only flag to allow the new "partial commit" semantics when paths are specified. The default is still the traditional --include semantics. Once peoples' fingers and scripts that want the traditional behaviour are updated to explicitly say --include, we could change it to either default to --only, or refuse to operate without either --only/--include when paths are specified. This also fixes a couple of bugs in the previous round. Namely: - forgot to save/restore index in some cases. - forgot to use the temporary index to show status when '--only paths...' semantics was used. - --author did not take precedence when reusing an existing commit.
