[troff]: Fix Savannah #64469 (`-o` out of bounds).
[troff]: Better handle inapplicable or out-of-bounds (but still
numerically valid) output page selection list (`-o` argument).
* src/roff/troff/node.cpp: New global Boolean
`was_any_page_in_output_list` tracks this datum; defaults false.
(troff_output_file::trailer): When finishing up, don't write a
"trailer" grout command (and vertical motion) if no page ever began.
Insted, throw a warning in category `range`.
(real_output_file::begin_page): Make `was_any_page_in_output_list`
true if any page is written.
Fixes <https://savannah.gnu.org/bugs/?64469>. Thanks to Dave Kemper for
the report.
Exhibit:
$ echo hello | ~/groff-stable/bin/groff -o 2
grops:<standard input>:5: fatal error: 'V' command invalid before first
'p' command
$ echo hello | ./build/test-groff -o 2 > /dev/null
$ echo hello | ./build/test-groff -o 2 -wrange > /dev/null
troff: warning: no pages in output page selection list
