I'm not quite sure what you mean there (did you intend to say
"appears to match the implementation"?).
The current documentation says
`-Wtrigraphs'
Warn if any trigraphs are encountered that might change the
meaning of the program (trigraphs within comments are not warned
about).
which is different to the documentation quoted earlier in this
thread. I agree that it seems clear enough.

I think that if you use `-Wtrigraphs', you should get the warnings
regardless of whether trigraph substitution is enabled or not.
That is the current behaviour, and matches the current documentation.
