FOO                     10  02.01.06   7:45 foo

where "FOO" is the short filename (aka 8+3 alias) and "foo" is the long
filename.

FOO                     10  02.01.06   7:45  foo

The short filename remains unaffected by the renaming operation, the
additional space between "7:45" and "foo" shows that the long filename
was changed.

The FindFirstFile call in

fh = FindFirstFile (name, &wfd);

around line 2430 in w32.c finds "c:/foo" due to the fact that
FindFirstFile is allowed to return a file whose short filename matches
the parameter "name" (provided - as I suspect - it does not find a file
whose long filename matches "name").
