Summary: quopri.py fix: escape single-dot lines
Initial Comment:
This is a patch against the CVS (head) version of
quopri.py, which ensures that the encoding never outputs
lines which consist of a single dot '.' (as recommended
by RFC 2049), since this can cause parts of messages to
get dropped when they are submitted via SMTP or via
/usr/lib/sendmail.
The patch fixes this problem by encoding the '.' as
'=2E' if it occurs on a line by itself.
In previous versions of quopri.py, line wrapping due to
the 76 character limit could cause single-dot lines to
be created; this does not appear to be a problem in the
current version because the line length is calculated
differently. However, a '.' on a line by itself may
appear in the input, so this case still needs to be
handled.
