Multiple fixes with respect to in-line macros:

* .No selects the default font; relevant e.g. in .Bf blocks
* no need to force empty .Li elements
* closing delimiters as leading macro arguments do not suppress space
* opening delimiters at the end of a macro line do not suppress space
* correctly handle delimiter spacing in -Tman
As a side effect, these fixes let mandoc warn about empty .No macros
