On Void Linux, we recently re-enabled installation of localized man
pages.  However, man(1) (version 1.14.5) behaves rather strangely on
such occasions. I have attached a tarball with the file structure I'm
currently diagnosing this issue in. The file list inside it is as such:


For starters, the default /etc/man.conf is as seen below:

manpath /usr/share/local/man
manpath /usr/share/man

In this initial case, `man kate` will open
/usr/share/man/ca/man1/kate.1, after, according to strace(1), calling
access(2) on the other files as well:

chdir("/usr/share/man")                 = 0
access("ca/man1/kate.1", R_OK)          = 0
access("pt_BR/man1/kate.1", R_OK)       = 0
access("man1/kate.1", R_OK)             = 0

In my opinion, this isn't intended behavior, since I don't have anything
(such as a LANG environment variable) that would indicate any preference
for the ca man page. If I add a `manpath /usr/share/man/pt_BR` entry to
the tail of man.conf, the same thing still happens; it's only if I add
it somewhere before the `manpath /usr/share/man` entry that I get the
pt_BR man page.

Interestingly, applying the patches discussed in [1] was enough for this
issue not to present itself. However, given that the problems discussed
there didn't seem at all related to my current issue, I don't know for
sure that the fix wasn't accidental; if it was, I would be interested in
getting a proper fix, and if it wasn't, I'd like to be sure of it.

Furthermore, as a feature request (that I would be willing to work on),
I believe it might be interesting to make man(1) smart enough to use man
pages from $manpath/$locale, where $locale could be $LANG itself and/or
$LANG stripped of the '.UTF-8' suffix (or even turned from 'll_CC' to

Finally, I would like to ask about the possibility of a mandoc release;
we are already carrying some patches for essential fixes, including the
ones from [1]. If there's anything that I could help with for that,
please let me know.

Happy new year,
