Hi there,

As far as I can tell, there may be two glitches in rcube_mime::wordwrap().

A message consisting of only one very long line (i.e. with no linebreaks) will not be wrapped at all if there are no blank spaces before the $width limit, but only behind it.

this-is-just-some-blabla-to-make-this-more-than-seventy-five-characters-in-a-row -- this message has no line breaks and will not be wrapped.

2nd: https://github.com/roundcube/roundcubemail/blob/master/program/lib/Roundcube/rcube_mime.php#L640
The result from mb_substr() is compared to false, but contrary to substr(), mb_substr() never returns false.
Because of this, a trailing whitespace or linebreak at the end of the last line might get dropped inadvertently.
