In directory genba:/tmp/cvs-serv6679/man

Modified Files:
        groff.man groff_diff.man 
Log Message:

* tmac/doc.tmac (doc-tag-list): Don't use \Z to assure that spaces
aren't stretched in a tag (this can fail with unformatted boxes).
Instead, insert a break and go back one line.

* src/roff/troff/input.cc (return_macro_request): If called with
argument pop macro twice.  We need this to trace `return'.

* tmac/trace.tmac: Handle `return'.
Fix typos.

* NEWS, man/groff_diff.man, man/groff.man, doc/groff.texinfo:
Document.

* tmac/groff_ms.man, doc/groff.texinfo: Improve documentation of
registers `FPS', `FVS', and `FPD'.
