Hmm, I like this because it is clear (if you know that dependancies
can be joined like that), I was thinking of trying to make a smaller fix
using pathsubst or subst, but that seems to not be as simple as I wanted it
to be.

Did you get those lines mixed up? I might be not understanding something
here.

I was actually planning something along the lines of 

             -e '/@@GITWEB_CSS@@/r $(GITWEB_CSS_NAME)' \
             -e 's|@@GITWEB_CSS_NAME@@|$(GITWEB_CSS_NAME)|' \

where I introduce the GITWEB_CSS_NAME variable, to be consistent with the
token in instaweb. This way we don't touch GITWEB_JS in the top level
makefile.

Also, I should update dependancies for instaweb, since those were
forgotten last time around. Just creating a short list of what the fix will
need for when I get home tonight.
