[PATCH] Allow multiple -m options to git-commit.

[PATCH] Allow multiple -m options to git-commit.

[Shawn Pearce]

I find it very convenient to be able to supply multiple paragraphs
of text on the command line with a single git-commit call.  This
change permits multiple -m/--message type options to be supplied
to git-commit with each message being added as its own paragraph
of text in the commit message.

The -m option is still not permitted with -c/-C/-F nor are multiple
occurrences of these options permitted.
