[PATCH] "Child" information in commit window - and cleanups

This adds "Child: " lines to the commit window, which tells what children
a commit has.

It also cleans things up: it marks the text widget as no-wrap, which means
that it doesn't need to truncate the commit description arbitrarily by
hand. Also, the description itself is now done by a common helper routine
that handles both the parent and the children.
