I did NOT say that Windows/DOS-style path support was the whole reason
for Cygwin.  Pay attention to your quoting/paraphrasing.

Not yet.  Cygpath certainly supports Windows-style paths.  Are you
claiming that places like that are the only place that it is "accepted"
to use Windows-styles paths (that is, if something like "ls 'C:\x\y'" quit
working, it likely wouldn't be fixed)?
