I wonder how the rule established by b315c5c (strbuf change: be
sure ->buf is never ever NULL) and at the beginning of strbuf.h
applies here. I think the current implementation of strbuf
happens to allow this, and it is very handy. Perhaps the rule
stated there should be loosened and allow copying the buf away
when you know you have stuff in there (i.e. ->buf != slopbuf).
Pierre, what do you think?
What the patch does itself is much nicer than the original.
