I agree.  Emacs practice calls for replacing "path" with "filename" or (better)
"file-name" here.

However, I would suggest replacing "windows" with whatever is the accepted term
used in Emacs names these days (win32?).  We do not want to confuse users.  This
is about Microsoft Windows file names; it is not about Emacs windows.
