bug#69536: 30.0.50; Runtime error happens with Tamago input method after recent change with obarry

[Mattias Engdegård]

Thanks for the report. That code seems to be quite old in style in general; it 
appears to use obarrays as some kind of poor man's hash table, so perhaps it 
even pre-dated the addition of hash tables to Emacs.

In any case, filling a vector with `nil` never was a correct was to make an 
obarray. It must be filled with the integer 0. Of course, today `obarray-make` 
is preferable.

Do you know if the Github repository (hrs-allbsd/tamago) is the closest we can 
get to an upstream source for this package? If so, open a bug report (issue) 
there. We will help explaining the problems.

Attached is an (untested) patch against Tamago. Maybe that will help you get by.
