As long as we're looking at that code, we probably want to do an audit to

Hm, I see that m_getfld() uses isspace() ... but since that hasn't seem
to broken just yet I am reluctant to mess with it. Other uses are in
MIME parsing ... I think that should be okay as long as the locale
character set is a superset of ASCII. Is that normally the case?
That makes me think that we should have an isasciispace() function
that we should use for things like header and MIME parsing since
those should always be 7-bit ASCII.
just say isascii(x) && isspace(x). this is actually necessary for any
test nowadays. if you're not using wchar_t and <wchar.h> then you have
to guard against false matches by non-ascii upper-register characters.
