Subject: Bugfix: When a line ends with '\ \"', don't strip the trailing space
X-Git-Tag: VERSION_1_14_5~173
X-Git-Url: https://git.cameronkatri.com/mandoc.git/commitdiff_plain/6773fbde9b5bf91ad32caf6aefb8902ba59181fa

Bugfix: When a line ends with '\ \"', don't strip the trailing space
because that turned it into a bogus line continuation.
