[Groff] a .text macro

[Bernd Warken]

Some months ago, there was a discussion on the renaming of `.nop' into
`.text'.  This would not be justified because an argument wtarting with
a dot/apostroph will be executed as a macro.

To define a real text macro there must be a way to provide a syntactical
"nothing".  Some escapes produce nothing in the output because they
define additional semantical elements.  How about the following?

.de text
.  nop \{\}\$*
..

Is this clean?
