So you did something that is unsupported, and now it breaks for you.

I'd almost say: you should have expected that.  HOWEVER, this makes you 
the perfect guy to actually do something about libification (which has 
been on my mind for some time, with the prospect of GitCheetah), and 
therefore you deserve a little help, IMHO.

I have.  The 80 lines that were removed are _exactly_ the 80 lines that 
were added (prepended with some #includes).

Like Lars said, the prototype of the only non-static function, 
sha1_file_to_archive(), was in archive.h, which is included from 
builtin-archive.c (where the big hunk was moved from), so there is no 
possibility of a breakage there.

It is no _functional_ change, but if Lars _uses_ the function in cgit, I'd 
say it would be a "courtesy fix" before 1.5.4.

Mind you, I would not propose to make libgit.a fully functional as a 
standalone library before 1.5.4.

But Lars contributed a lot, and did a very good job of collecting git 
patches back in October.  Therefore I think that he deserves a little 
extra attention, even if it does not fix a bug in git proper.

Ciao,
Dscho
