I always forget about history view, probably because I never use it.

A-hem. (whistles innocently)

I know it's neither good form nor good webdesigner attitude, but I
stopped caring about IE a long time ago. I understand however that
some ancient versions of Mozilla browsers might have the same issue
too.

A possible alternative could maybe do without images and just use
borders and backgrounds of an 8x8 fixed-size element. Wouldn't look as
nice, probably, but should render decently in everything that supports
CSS1.

No particular reason. I didn't check for syntax preferences regarding
this in gitweb, or I would have noticed there was a preference for the
one you mention.

Yep, good point.

Indeed I should.

It's within a span element so I was trying to stick to single line in
the HTML source.

I did notice that the final br didn't seem to affect the box height,
so I didn't bother looking at ways to do without it, but it's probably
nicer to not have it.
