Added two new requests `de1' and `am1' which are similar to `de' and

`am' with the difference that compatibility mode is saved on entry,
switched off during macro execution, and restored on exit.

* src/roff/troff/input.h: Added two new special characters
(COMPATIBLE_SAVE, COMPATIBLE_RESTORE).
* src/roff/troff/input.cc (input_iterator): Added two member
functions `save_compatible_flag' and `get_compatible_flag'.
(input_stack): Ditto.
(string_iterator): Ditto.  Also add private member
`saved_compatible_flag'.
(token::next): Use COMPATIBLE_SAVE and COMPATIBLE_RESTORE.
(calling_mode): New enumeration.
(do_define_macro): Use it.  Insert COMPATIBLE_SAVE and
COMPATIBLE_RESTORE at the beginning and end of macro, respectively.
(define_macro, define_indirect_macro, append_macro, ignore): Use
`calling_mode'.
(define_nocomp_macro, append_nocomp_macro): New functions.
(init_input_requests): Updated.
(do_request): Rename local variable `saved_compatible_flag' to
`old_compatible_flag'.
* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

* tmac/an-old.tmac: Use `de1' instead of `de' request for all
public and trap-invoked macros.  As a consequence, the man macros
work in compatibility mode also.


* Makefile.in: Use $(mandir).
