Shouldn't _man calculate man page completions using `man -w' rather
than $manpath? For me, $manpath is always empty, so man doesn't
complete anything.
Is it safe to assume that `-w' is present in all sensible versions of
man?

No. It is not supported on our system at least. And here I do need
$MANPATH.

Hmm. What about man --path? Maybe only the GNU man has it.
Sounds like we need some way of intelligently figuring out a solution
for both scenarios. Does `man -w' return an error of some sort on
your system which we could test for?

Well, exit code != 0. I have no idea, how reliable it is (different
versions etc)

Same here for Digital Unix. Maybe we should test $OSTYPE?

The only man I can find which does support -w or --path is the GNU one.
The exit code of != 0 seems fine on the systems I've looked at provided
stderr is redirected.
What are you trying to achieve with man -w - find a default manpath to
use if $manpath is unset? As far as I can tell man -w only gives you the
location of a specific man page which isn't entirely useful for finding
a default manpath as the default can (and often will) contain more than
one directory. The only way I know of finding the default manpath is by
running the man binary through strings. Maybe we could use a for loop to
guess possible man directories and check them.

Yes, a la `_x_color'.

No, the GNU man displays all the man paths it will use if invoked as
`man -w':
-w or --path
Don't actually display the man pages, but do print
the location(s) of the files that would be format-
ted or displayed. If no argument is given: display
(on stdout) the list of directories that is
searched by man for man pages. If manpath is a link
to man, then "manpath" is equivalent to "man
--path".
-W Like -w, but print file names one per line, without
additional information. This is useful in shell
commands like man -aW man | xargs ls -l

In the GNU case, you can just grep /etc/man.config for `^MANPATH '.

I'd rather keep guessing as a last resort. Maybe try man -w and check
the exit code, then
if [[ -r /etc/man.config ]]; then
...
?

It seems that GNU man itself varies. The GNU man on the debian linux
system I have access to at work prints:
What manual page do you want?
in response to -w with no argument and has no -W option. Note that it
does return an exit code of 1 though so we can still use man -w if we
check the exit code.

That must be specific to your linux distribution as opposed to GNU man.

That's probably the best approach as long as we don't find a system that
breaks it.

Just to complicate things further, man_db (as used by Debian)
uses an /etc/manpath.config that looks like this:
MANDATORY_MANPATH /usr/man
MANDATORY_MANPATH /usr/share/man
MANDATORY_MANPATH /usr/X11R6/man
MANDATORY_MANPATH /usr/local/man
#---------------------------------------------------------
# set up PATH to MANPATH mapping
# ie. what man tree holds man pages for what binary directory.
#
# *PATH* -> *MANPATH*
#
