Still, the problem is that the intended meaning of
convert-standard-filename is unclear (what should it do on relative
file names?), and that the functionality require by the OP is not quite
the one provided by convert-standard-filename, AFAIK (and I don't think
we have exactly what he wants).
My understanding is:
- convert-standard-filename is to convert a predefined name, which may
be mentioned in docs, using mostly Unix conventions so that it works
on whichever OS we're using. E.g. it may do things like map ".emacs"
to "_emacs".
- the function Sam needs is one that converts from "file name using
conventions used in the system in which Emacs is running" to "file
name referring to the same file but such that Emacs can access it".
Doing things like "However, on Windows and DOS, replace invalid
characters" is not the right thing to do.
BTW the function he wants is also the function that should be applied to
files names received in command-line-args and as args to emacsclient
(as was recently requested by some other poster).
