I thought of the check for whether or not it exists when I was working on
it, but I wasn't sure what all to check for. I only use it to run
executable files so for my case it's easy, but I wasn't sure what all might
get put in there. When I asked in the irc channel there was some mention
of things other than files that would show up in the list, so I decided not
to worry about the check and let the user prune bogus history items some
other way. I think someone put together an example to do the pruning that
was basically a one line bash script which could be run separately from
dmenu itself.
