file-name-all-completions vs. completion-ignored-extensions

[I reported this last May and haven't seen any response, so I'm trying again. This time I'm attaching a patch.] In XEmacs 21.4.6, and also in XEmacs 21.5-b4: The function 'file-name-all-completions' does not behave the way its documentation says it should. Namely, its documentation says: File names which end with any member of `completion-ignored-extensions' are not considered as possible completions for PARTIAL-FILENAME unless there is no other possible completion. `completion-ignored-extensions' is not applied to the names of directories. I have set 'completion-ignored-extensions' to include "~" and ".log". I have a directory 'blah' with these files in it: new.el new.el~ nn.log If I run (file-name-all-completions "n" "blah") I get ("new.el~" "new.el" "nn.log") whereas I was expecting just ("new.el"). (On the other hand, 'file-name-completion' has the same passage in its documentation, and (file-name-completion "n" "blah") gives "new.el" so it is paying attention to completion-ignored-extensions.) I would recommend deleting the above paragraph from the documentation for file-name-all-completions; among other things, this would make the behavior consistent with GNU Emacs. The documentation for the variable completion-ignored-extensions needs to change, as well, since it refers to file-name-all-completions. I've attached a patch (against XEmacs 21.4.6, but seems to work with 21.5-b4, too) to make these changes. (Sorry, I haven't downloaded the CVS version.) -- J. H.
