In the "UNIX processing handbook", 1988, there is a mention of .NP macro for ms macros. I cannot find it groff 1.22 ms. Has it been dropped?
Also, if I put .NP in my document, it has no effect, and no warnings/errors are given. Is this normal groff behaviour - quetly to ingore all unrecognised macro requests? Is there an option to issue warnings for all not recognised requests? Thanks Anton
