| The DOS/Windows drive letters are ASCII, so I think [A-Za-z] should be

I remember that you deliberately used A-z to match those other six
characters.  My point is that if you really want to depend on the C
local, then you should make it explicit.  With some other locales, A-z
contains characters that are not valid drive letters.  So it's more
portable to enumerate the acceptable letters.  Now (with ibm360-linux)
we have a legitimate reason to accommodate EBCDIC.

| those 6 letters, which are almost never used.)
