Details:
The MANPATH environment variable may be prefixed or suffixed by a bare colon
(:) character or contains a double colon (::). These colon characters have the
meaning to insert respectively before, after or between the man directory list
determined from the content of the man configuration files.
See the description of the MANPATH variable in the manpath man page
<http://man7.org/linux/man-pages/man1/manpath.1.html#ENVIRONMENT> for the
complete reference.
The *groffer* tool does not support these colon-specific values in MANPATH and
ends in error when facing them:
$ echo $MANPATH
/usr/share/man/mpich-x86_64:
$ man -w ls
/usr/share/man/man1/ls.1.gz
$ groffer ls
main_do_fileargs(): ls is neither a file nor a man page; at
/usr/share/groff/1.22.3/groffer/main_subs.pl line 1548.
groffer: empty input
$ groffer -v
groffer 2.2.5 is part of groff version 1.22.3.

Looking in _/usr/share/groff/1.22.3/groffer/man.pl_, the _man_setup()_
function should be adapted maybe to only rely on the output of the *manpath*
command as this command could return the manpath system configuration needed
when MANPATH is prefixed/suffixed by a colon character or contains a double
colon.
