                 Summary: [PATCH] Reverse the change '.it' to '.itc' for the
simple macros

    _______________________________________________________

Details:

 The simple font (one letter) and size changing (SM, SB) macros don't need
a request '.itc' to do their job.
That request can extend its influence too far.

  An example from "groff_out.5.man" shows that:

.B D\c
\~commands are assumed to be device-specific.

  A transparent line indicator (\!) should work for those macros if more
than one line is asked for.

  Macros that operate on the whole next input line do benefit from an '.itc'.
The next line can then be split into several source lines (for example all
beginning with a macro-call).

  An alternative could be to use a transparent line indicator (\!).
