Improve implementation of CRE-stack-flattening in map_variable_attnos().

I (tgl) objected to the obscure implementation introduced in commit
1c497fa72.  This one seems a bit less action-at-a-distance-y, at the
price of repeating a few lines of code.

Improve the comments about what the function is doing, too.

Amit Khandekar, whacked around a bit more by me
