>Description:

The "-" shortcut in MLINKS doesn't work any longer.  This could be
used as a ditto mark if you had a number of <source, target> tuples
where <source> was always the same.  Now a symlink to a literal
file "-" is created.

See ports/devel/libevent for an example port that uses this.

Since the code to handle "-" is still there in the __pmlinks
assignment, I assume this is a bug rather than an intentional change.

>How-To-Repeat:

Install ports/devel/libevent.

$ ls -l /usr/local/man/man3/event_dispatch.3*
