@w, or @c) because there isn't an index entry which is
the command name exactly
Ok, I changed those @findex entries to be just "w" and "c".
As for comprehensively checking all commands, long ago I wrote a script
to check consistency of the command lists in the reference card, the
"Command List" appendix, and the tp implementation. It's
doc/refcard/txicmdcheck. It would be easy enough to extend it to check
against the fnindex too. I'll see if I can hack that in, unless you'd
like to. (One way, since there are many @findexed things which are not
@-commands -- possibly another area for change, but would be a fairly
extensive project.)
