Description:
        completion does not understand Windows filename syntax

Repeat-By:

Cgywin has been moving in the direction of using standard Windows
filenames.  At this point if HOME is set to c:/users/hedrick, the
"pwd" command will print it in the form c:/users/hedrick, not the old
/cygdrive/c/users/hedrick.  However if I type "cd /users/hed<esc>" it
doesn't complete.  Nor does "cd c:/users/hed<esc>".  Completion only
works if I type "cd /cygdrive/c/users/hed<esc>".  If I were working
in an environment with only Gnu tools, I'd just mount the drives
as /c, /d, etc.  However Windows tools won't understand that syntax.
So I agree with the recent tendency to make Gnu tools understand
and output using the drive letter.  It seems like someone hasn't
yet converted readline.
