Hi,

after updating from cygwin 1.5.19-4 to 1.5.21-1 cygpath seems to show a bug
when called with the --long-name (or -l) option:
Assuming that the filename "12345678901234567890" does NOT exist in the
current dir, cygpath shows the following output:

$ cygpath -m -l 12345678901234567890
123456789012#

$ cygpath -w -l 12345678901234567890
123456789012xx  7890
                        ^^
                 not printable characters

$ cygpath -w 12345678901234567890
12345678901234567890

$ cygpath -u 12345678901234567890
12345678901234567890

$ touch  12345678901234567890
$ cygpath -w -l 12345678901234567890
12345678901234567890

$ rm 12345678901234567890
$ cygpath -w -l 12345678901234567890
123456789012xx  7890
                        ^^
                 not printable characters

i.e., as long as the file name does not exist and exceeds a certain length,
it gets scrambled with the -l option.
Without the -l option, in posix format, or if the file exists, the output is
fine.

Can you confirm this bug? Is there a workaround?

Matthias.
