    _______________________________________________________

Details:

Prevent mdoc(7) Bl with trailing -width or -offset from picking up old args.

When checking whether there is another argument to a Bl macro,
do not inspect the argument list because it is never cleaned
and may contain arguments from previous macro invocations.
Instead, inspect the argument count which is always up to date.

The second attachment is a sample file exhibiting the problem.

The patch in the first attachment was verified by rebuilding
the whole set of OpenBSD manuals and by running the whole mandoc
test suite.  No regressions were found.
