This question applies for this function and a few more functions in this
patch that has the same characteristics.
If we're in a state when we need to return non-zero, we don't do any
cleaning (that is strbuf_release()). Since this file is in the part
called libgit AFAIK, shouldn't we always clean after us?
Would it make sense to have different return values for different
errors?
I do like the comments above the function, more functions (at least
non-static ones) should follow this good style IMHO.
