I see, thanks.

OK... I studied it... first what's in repolink has some duplication of 
code that I added a patch to clean out.

In a second patch I added a helper cgit_repo_create_url() that does the 
core function without urlencode into a pair of strbufs, one for before 
any ? and one including the ? and anything after.  They can point to the 
same strbuf if the caller doesn't care.
