Yes, Aharon told me separately.  I see nothing to do at present.  There
are four index entries in the gawk manual which match `sub':

* sub function <1>:                      String Functions.
* sub function:                          Using Constant Regexps.
* sub function, arguments of:            String Functions.
* sub function, escape processing:       Gory Details.

I see no way, at present, for any info program to know which one to
prefer.

What we need is a way to mark an index entry as the "defining" one.
Then the readers could prefer that one when there is a match.
There are lots of other index improvements needed as well.
Unfortunately I have no ETA at present for implementing them.
If someone else wants to make it happen ...

Thanks,
