[bug #60782] groff: doesn't exit with status 1 when .ab request used with -Thtml

[G. Branden Robinson]

Update of bug #60782 (project groff):

                Severity:              3 - Normal => 4 - Important

Follow-up Comment #1:

This is really just egregiously bad.

The cause of the problem is not obvious; I checked src/roff/groff/pipeline.c
and everything there seems to be in order.  All commands in the pipeline _that
get forked off_ exit with status zero.

It is troff itself that should be exiting with status 1, but that's not run as
part of the pipeline.

Sample of instrumented output:


$ ./build/groff -F ./build/font -Thtml -t -man ./build/tmac/groff_man.7
./build/src/preproc/eqn/neqn.1 >/dev/null
GBR: execing soelim as pid 36382
GBR: execing tbl as pid 36383
GBR: execing pre-grohtml as pid 36384
GBR: execing post-grohtml as pid 36385
GBR: pid 36382 exited with status 0
GBR: pid 36383 exited with status 0
GBR: pid 36384 exited with status 0
GBR: pid 36385 exited with status 0
