There's no functionality like this at the moment.  It looks like you're
putting bug references in the subject, so presumably adding a filter
around the subject in ui-log.c is what you're looking for.

We currently pass the subject through the commit filter for the commit
UI, so I guess that could be reued for the log view.

The problem is that in the log UI the subject is a hyperlink but all
our current filters act on plain text.  I guess you could pull apart
cgit_commit_link() to allow opening the <a> tag as a separate step and
have the caller output the body of that tag, which could be passed
through a filter.  But I haven't thought through all of the edge cases
here - what if the filter wants its own hyperlink, like your bug link?
Would it be better to call the filter with the href as an argument, so
it's up to the filter to output the anchor tag around the subject?
