Maybe, but maybe the user doesn't want to care.  "lib" is a valid name
to pass to man, so completion should provide it.  After all, M-x man
can show *all* the pages found, so the choice of section can be
made later.

Yes, a better way to do it would be to consider "3erl " "as
a directory", i.e. the completion table should recognize it and set
a "boundary" right there.  It doesn't need to provide completion for the
section names.

You could also do it via M-x man RET 3erl C-a TAB since a * is
implicitly added at point.
