I started to implement a 'log-filter' but ran into some design problems:

  * My initial use case was to create a link for 'fixes #123' style 
commit messages.  However, the entire log summary snippet is already 
wrapped in an <a href> to commit/?id=foo.  I wouldn't want to loose that 
or make it uglier in service of convenience bug tracker links.  Since 
html links can not be nested I'm not sure what options that leaves.

  * With showmsg=1, should the commit or log filter be used?
