[PATCH] handle attachment filenames starting with "-"

[James Cook]

From a brief IRC discussion Dec 7:

If when editing in mcom/mfwd I write an "attach" line with a filename
starting with -t, I see "file: unknown option -- t" before the "what
now?" prompt. (I encountered this naturally when I tried to attach
a file that some online service had decided to name "-tickets.pdf".)

The below patch fixes it, following Leah's suggestion on IRC.

Based an a quick look, contrib/msendmail might benefit from a similar
patch, but I don't use that tool so I haven't tried.

I also noticed I can't run e.g. "mcom -attach -t", I guess due to
the way option parsing works. My patch doesn't address that.
