commit ea32b7d0462813fc3e7c423efb6d805273df9edd
Author: G. Branden Robinson <address@hidden>

    makevarescape.sed: Add breakpoints, spaces, and ".
    
        * makevarescape.sed:
          + Escape plain spaces and double-quotes (ASCII 32 and 34) so
            that bad things don't happen if they are embedded in a Make
            variable expanded in a man page @THUS@ _and_ given as an
            argument to a macro that distinguishes its parameters, such
            as .IR.
          + Add discretionary breaks after groups of slashes not
            preceded by a space; e.g., transform "/usr/bin/groff" into
            "/usr/\:bin/\:groff".  Will also work on URLs
            ("https://\:example.com/\:page.html";) in case we need that.
