Some projects keep a ChangeLog which every commit modifies. This
makes the graph a very uninteresting single line of commits. It is
sometimes useful to see how the graph would look if we ignore the
ChangeLog file.
The new -x option is useful in situations like this. It can be
repeated several times to ignore many files. Each argument is saved
to a temporary file and "grep -v -f $TEMPORARY" is used to filter out
the file names you want to ignore.
Also added a minimal test case and documentation.

-------
+-x <pattern>::
+ Ignore files that matches the given grep pattern. Can be

<patchname>.
