Correct. It's not a simple string compare though, groff's info manual
explains more.
info groff 2>/dev/null |
sed -n '/Node: Operators in Conditionals/,/^File:/p'
You can get close with De Morgans to turn a|b into !(!a&!b) and chain
two .ifs to do the & with the first being a .ie so the .el mops up, but
it misses one of the cases.
BTW, do any info experts know how to have info(1) format just that node?
-n doesn't work to visit that node, it thinks it doesn't exist even
though it's printing that as the node name. I guess it's looking
somewhere else for -n.
$ info -n 'Operators in Conditionals' groff
info: Cannot find node `Operators in Conditionals'.

Cheers, Ralph.
