r5813: Fix bug found by Jim McDonough <jmcd@us.ibm.com>

Win9x can send a resume name of "..". This will cause the parser to
complain (it thinks we're asking for the directory above the shared
path). Catch this as the resume name is only compared, never used in
a file access and replace it with "..".
