Hi,

Local: Emacs on Windows 7.
Host:  Linux
Tramp from Windows 7 to linux

A further information: it is about backup. When I setup
tramp-backup-directory-alist which will make it backup serverside. However,
It concat !driver_c to the backup file name.

I have setting ("\\.md$" . "~/.emacs.d/backup-tramp/mdfiles") in
tramp-backup-directory-alist. The backup file in the server is
"!drive_c!plink!!user@host!!!opt!host!path!Ava!_summary.md.~1~"

The "!drive_c" comes very strange.

Best Regards,
Shuguang
