Send STRING to the standard error output; this is
very useful for printing debugging messages among
other things. STRING is read in copy mode.
Copy-in mode:
When 'gtroff' reads in the text for a macro, string,
or diversion, it copies the text (including request
lines, but excluding escapes) into an internal buffer.
Escapes are converted into an internal form, except for
'\n', '\$', '\*', '\\' and '\<RET>', which are evaluated
and inserted into the text where the escape was located.
This is known as "copy-in" mode or "copy" mode.
