Bugzilla Bug 37778

If there is no message catalog for a given locale, for instance sv_SE, man will
show an annoying message like this:

  Failed to open the message catalog "man" for locale "sv_SE"
  (NLSPATH="/usr/share/locale/%L/%N")

Contrary to what the man manpage seems to indicate, I can't avoid this message
by having man search for english messages by setting LC_MESSAGES to an English
locale.

According to the man manpage LC_MESSAGES can be used to set the locale to use
for messages. If not LC_MESSAGES is set, then man will look for the value of
LANG instead. But currently man operates in the opposite way, looking for LANG
first and then LC_MESSAGES (or LC_ALL, which should override all other LC_*
variables).


Reproducible: Always
Steps to Reproduce:
set LANG to "sv_SE"
set LC_MESSAGES (or LC_ALL) to "en_US" (or any other locale - has no effect)
try to use a man page that doesn't exist
Actual Results:  
Output:
  Failed to open the message catalog "man" for locale "sv_SE"
  (NLSPATH="/usr/share/locale/%L/%N")

  What manual page do you want?

Proposed fix - change the order in which man looks for locale related
environment variables to find message catalogs:

                fprintf(stderr,

does this apply to man-1.5m ?

Apparently, there is a solution. Man (even version man-1.5m-r1) is broken.

I applied the changes, and now 'man' works just fine. 

I'm attaching a new ebuild with the patch that works fine for me. Please test
and integrate into portage tree.

Created an attachment (id=37407) [details]
Patch that fixes the catget problem (see comments)

Created an attachment (id=37408) [details]
Ebuild that uses the catgets patch

ok, thanks for doing the footwork :)

fixed in 1.5m-r2
