PATCH: _brace_parameter: add (-)

[Mikael Magnusson <mikachu@gmail.com>]

I looked at adding fc -s which is probably not that hard, but I noticed
that fc -e<tab> and fc -e <tab> both don't complete commands which it
looks like they should.

(the completer has -e+ which means it only expects -ecommand but in
practice -e - also works, as well as the manpage listing it with the
space when talking about -s.
