[PATCH] Automatically line wrap long commit messages.

[Shawn Pearce <spearce@spearce.org>]

When using -m on the command line with git-commit it is not uncommon
for a long commit message to be entered without line terminators.
This creates commit objects whose messages are not readable in
'git log' as the line runs off the screen.

So instead reformat log messages if they are supplied on the
command line.

 This one might cause some problems for people.  It requires
 'fmt' in order to use log messages on the command line as well as
 some users may not like having their log messages line wrapped.
 I'm open to suggestions for how to deal with this but personally
 this is one feature which I put into pg's commit tool that I miss
 dearly when working with core GIT.
