[Edbrowse-dev] wordexp again

[Karl Dahlke <eklhad@comcast.net>]

I made one common routine to protect a file name or directory name from
shell expansion, it's the same code I was using before, but now it is shared
between the directory scan and the plugin commands.
Ok, that's good software practice, but it exposed a bug
that I think was there all along.
You can't edit a directory with a backslash in it.

mkdir "a\\b"
cd a?b
touch foo bar
cd ..
edbrowse a?b

Try it before or after my latest push.
The files therein just don't show up,
because wordexp doesn't expand a\\b/* properly.
and that is the proper escaping.
At the shell prompt
ls a\\b/*
works fine.
And it all works through the plugin system, i.e. a\b.pdf becomes
pdftohtml a\\b.pdf
This seems to be a bug in wordexp, at least my wordexp,
and I'm really not sure what to do about it.
