autofs-5.1.6 - fix trailing dollar sun entry expansion
From: Ian Kent <raven@themaw.net>
In modules/parse_sun.c:expandsunent() if we see "$ " or "$<NULL>" in a
the entry it can't be a macro, and the value can't be quoted since '\'
and '"' cases are handled seperately in the swicth, so treat the
character as a valid entry character.
