+This variable lists transforms to apply to buffer's file name before

-Each transform is a list of the form @code{(@var{regexp}

+expression to match against the file name; if it matches,
@code{replace-match} is used to replace the matching part with

All the transforms in the list are tried, in the order they are listed.
When one transform applies, its result is final;
no further transforms are tried.

On MS-DOS filesystems without long names this variable is always
ignored.
