funcnest and recursion

[Ondrej Oprala]

Hi, there've recently been a few bug reports against bash on RH BZ,
saying that bash can't handle infinite recursion the way zsh or ksh can.

Looking at execute_cmd.c, there are the  funcnest{,_max} variables
and a piece of code using them in execute_function().

Will funcnest_max be set to non-0 in upstream code in the future?
Or is it just there for the downstream maintainers to set it if they
see it fit?

Thanks,
Ondrej
