lynx-dev DOS patch

[Doug Kaufman]

The following patch fixes two problems with the DOS port. The patch
to LYGlobalDefs.h makes the context help work again (the fragments
in lynx_users_guide.html are still numerical rather than mnemonic).
The patch to LYMail.c prevents ^C during an attempt to send mail from
causing lynx to exit after returning from the mail attempt.

I found another bug, present at least since dev.17, where lynx can't
download files if it is started from one of the root directories of a
disk drive, since it is trying to write to "c:\\file.ext", rather than
"c:\file.ext". I'll try to look for the fix when I get time.
