Commit of patch floated on discuss@ a few days ago: if an in_line scope

has not been opened and closing punctuation is encountered AND the macro
is marked as accepting no-content (or `Li'), then open an empty scope.

Added regression tests for `Fl' and `Li' testing this behaviour.

Also, squeeze hyph0.in tests into the last characters of each line so
that groff doesn't hyphenate and break the test.
