New commands \D'Fr ...', \D'Fc ...', etc. for orthogonality.

Make \D'f ...' move horizontally again for backwards compatibility.
Replace it with \D'Fg ...' where appropriate to avoid dependency
on horizontal resolution.

* src/roff/troff/input.cc (do_get_long_name): New function.
(get_long_name): Call it.

(read_draw_node): Handle `\D'Fx ...' by calling ...
(read_color_draw_node): New function.

(read_rgb, read_cmy, read_cmyk, read_gray): New optional argument
`end'.
Pass it to `do_get_long_name' which is used instead of
`get_long_name'.

* src/libs/libdriver/input.cc (color_from_Df_command): Remove
unnecessary value guard.
(parse_D_command) <'f'>: Add horizontal shift.

* src/preproc/grn/hgraph.cc (HGPrintElt) <POLYGON>: Use \D'Fg ...'.
* src/preproc/pic/troff.cc (troff_output::set_fill): Ditto.
(FILL_MAX): Removed.

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

* src/roff/troff/input.cc (do_name_test, do_expr_test,
do_zero_width): Push `\n' if closing delimiter is missing.

(token::next) <ESCAPE_NEWLINE>, <'\n'>, <'\ '>: Reset `have_input'.
<'F'>: Make \F non-transparent at the beginning of line.
(process_input_stack) <token::TOKEN_CHAR, token::TOKEN_NEWLINE,
token::TOKEN_REQUEST, token::TOKEN_BEGIN_TRAP>: Don't handle
`have_input'.

(define_color): Free color in case of reassignment.

* doc/groff.texinfo (@Defesc, @DefescList, @DefescItem,
@DefescListEnd): Use @Var, not @var.
Fix all calls.

* src/preproc/grn/hgraph.cc (HGPrintElt): Fix typo.

* src/preproc/pic/object.cc (object_spec::~object_spec): Free
`shaded' and `outlined' arrays.
(object_spec::object_spec): Initialize `shaded' and `outlined'.
(graphic_object::set_fill_color, graphic_object::set_outline_color):
Use strsave.
(closed_object::set_fill_color): Ditto.
* src/preproc/pic/troff.cc (troff_output::set_color): Use strsave
instead of strdup.
(troff_output::reset_color): Use a_delete instead of free.
* src/preproc/pic/main.cc (do_file): Free `out' in case of error.
