Update of bug #60913 (project groff):
Severity: 2 - Minor => 3 - Normal
Summary: suboptimal diagnostics when (mis)using .evc =>
suboptimal diagnostics and spurious output when (mis)using .evc
_______________________________________________________
Follow-up Comment #1:
Also, when .ev and .evc are misused, they cause empty lines in the output
because the validation logic performs early returns without calling
skip_line() to discard the newline at the end of the control line (and any
other stuff before it).
$ cat EXPERIMENTS/envbad.groff
.ev \" environment stack underflow
.evc nonexistent \" indeed it doesn't exist
.pl \n[nl]u
$ groff -Tutf8 -E EXPERIMENTS/envbad.groff | wc
1 0 1
$ ./build/test-groff -Tutf8 -E EXPERIMENTS/envbad.groff | wc
0 0 0
