Status: Ready for Merge => In Progress
_______________________________________________________
Follow-up Comment #4:
I found another case. This is from groff Git HEAD.
$ nl EXPERIMENTS/eqn-delimited-64105.roff
1 .EQ
2 delim $$
3 .EN
4 foo bar $x = 1
$ ./build/eqn -Tascii EXPERIMENTS/eqn-delimited-64105.roff >/dev/null
./build/eqn:EXPERIMENTS/eqn-delimited-64105.roff:3: fatal error: unterminated
inline equation; started with '$', expecting '$'
$ ./build/eqn -N -Tascii EXPERIMENTS/eqn-delimited-64105.roff >/dev/null
./build/eqn:EXPERIMENTS/eqn-delimited-64105.roff:3: error: unterminated inline
equation; started with '$', expecting '$'
This is only partially a regression from 1.22.4, because that _eqn_ got the
number wrong the other way if `-N` wasn't specified.
$ eqn -Tascii EXPERIMENTS/eqn-delimited-64105.roff >/dev/null
eqn:EXPERIMENTS/eqn-delimited-64105.roff:5: fatal error: unterminated '$' at
line 4, looking for '$'
$ eqn -N -Tascii EXPERIMENTS/eqn-delimited-64105.roff >/dev/null
eqn:EXPERIMENTS/eqn-delimited-64105.roff:4: missing '$'
