I get a completion for a file name that does not match my predicate
function with read-file-name. This problem seems to happen when there is
just one file in the directory. Maybe this problem is w32 specific since
the completion also returns "../" and "./". (Are these seen on other
systems too?)
To try this put just one file in a directory. This file should NOT match
predicate below (use for example temp.txt). Set default-directory to
this directory. Then eval
(defun image-predicate(url)
(or (file-directory-p url)
(string-match "\\.\\(?:png\\|jpg\\|jpeg\\|gif\\)$" url)))
(read-file-name "File: " nil nil nil nil 'image-predicate)
Press M-Tab to complete and see what happens. I get a hit for that file
(temp.txt) that does not match the predicate.
If I put another non-matching file there completion gives just "../".
w32. GNU Emacs 22.0.50.1 (i386-mingw-nt5.0.2195) of 2006-03-28.
