I don't know how this patch will affect the difficulty of enhancing it to
handle MIME attachments later, but let's say we won't worry about it for
now, because we do not even know if we want to do so at this moment.
I fixed up some style issues locally before applying, but please be
careful next time.
- One SP after a keyword used in syntactic constructs (e.g. "if (cond)",
not "while(cond)"); your patches were fine wrt this;
- No SP after a function (e.g. "memcpy(args...)", not "memcpy (args...)").
Also please be careful when calling get_sha1_hex(); an unsuccessful call
to this function is allowed to clobber the buffer. In addition to the
style fixes, I squashed something like this (not exactly this).
Thanks.
