It can't spit out _all_ of them because there are several that simply
aren't meaningful while a control line is being read.
These fall into two groups.
1. tab and field state; if you're not on a text line, these have no
meaning (there are several of these)
2. (just one datum) whether the current line has been interrupted;
that's impossible
$ printf '.\\cpev\n' | ./build/test-groff
troff:<standard input>:1: error: expected identifier, got an escaped 'c';
treated as missing
But that seems to be about all that `pev` can't report.
