Hi.

I'm the emacs packager in the Mandrake Linux distro.

i've find out that emacs-21.3 dired mode (really dired-move-to-filename) is
confused by locales that've quotes in month names.

this bug has been seen on ix86 machines running mandrake linux 9.1 and mandrake
linux cooker.

the following packages were installed on these machines:

address@hidden ~ $ rpm -q glibc locales{,-br} emacs
glibc-2.3.2-4mdk
locales-2.3.2-2mdk
locales-br-2.3.2-2mdk
emacs-21.3-5mdk

locale was configured as

address@hidden ~ $ cat .i18n 
LC_TELEPHONE=br_FR
LC_PAPER=br_FR
LC_NAME=br_FR
LC_CTYPE=br_FR
LANGUAGE=br:fr_FR:fr
LC_NUMERIC=br_FR
LC_MEASUREMENT=br_FR
LC_MONETARY=br_FR
LC_TIME=br_FR
LANG=br_FR
LC_IDENTIFICATION=br_FR
LC_ADDRESS=br_FR
LC_MESSAGES=br_FR



Description:
============

emacs dired mode is confused when file date is displayed in locales that have
non alphabetic characters.

eg: i use breton locale (locale used in britanny, west area of france) where
February localized name is C'Hwevrer (C'H being a character of the breton
alphabet, noted as the three charaters "c", "'" and "h").

the problem is that the "'" single quote character confuse dired mode

English month | breton month
--------------+-------------
January       | Genver
February      | C'hwevrer
March         | Meurzh
April         | Ebrel
May           | Mae
June          | Mezheven
July          | Gouere
August        | Eost
September     | Gwengolo
October       | Here
November      | Du
December      | Kerzu

How to reproduce
================

- locate a file dating from february, or alter the system clock to return back
  to february and touch a file to date it from february

- run "LC_TIME=br emacs" (you need the /usr/share/locale/br/LC_TIME file from
  glibc locales)

- open the directory where there's a "last altered in february" file

- try to open it in dired mode by typing enter on it

eg, when i open on my local hard disk the /pub/bzh.me/keltia/ directory, emacs
open a dired buffer whose content is:
>===============================================================================>
> /pub/bzh.me/keltia:

when i scroll the files through the down key, the cursor is on the first letter
of the file name.

but when i go on Makefile entry, the cursor goes at the beginning of the line
instead of goring on the first "M" of Makefile. when i type <enter>, emacs
display "No file on this line" in the minibuffer window and
"dired-move-to-filename: No file on this line" is inserted in the *Messages*
buffer.

obviously, dired seems confused because of the single quote in the date field
that prevent it to parse the Makefile file line in the dired buffer

if your system does not have the britton locale (iso code lang code being
"br"[0]), you can get it from glibc sources

[0] "br" lang code is not the brasilian portuguese code which is pt_br (but "br"
    country code does be the brasil one)
