SET-WORD! not gathered if in GROUP! inside PATH! in FUNCTION

[hostilefork]

>> z: "will this be overwritten"
== "will this be overwritten"

>> foo: function [x] [
    obj: make object! [y: 10]
    obj/(z: "yep" 'y): x
]

>> foo 100
== 100

>> z
== "yep"

The enumeration in COLLECT-WORDS/DEEP only considers BLOCK! and GROUP! values when descending, but GROUP!s or BLOCK!s in ANY-PATH! are not considered.

Ren-C has gone ahead and made it collect inside of paths...though the concept of using SET-WORD! as the cue for auto-collection is considered suspect at this point:

So not calling it "resolved" just yet...

This is a bit more uncertain with new rules on PATH!, and stepping away from locals-gathering FUNC. :-/

For now, paths are skipped...as it would involve some special handling to deal with them, as they are different (not necessarily array-like, could be compressed)
