Talking about nuking CYGWIN settings, I have at least two more candidates:
"envcache" Did we ever had a problem which could be attributed
to this setting?
"export" Does anybody really set CYGWIN settings in the registry?
Shouldn't we drop fetching CYGWIN settings from the registry
entirely?
"proc_retry" Does it really help?
Personally I would also remove "strip_title", "display_title", and
"upcaseenv", but that's just me.

No worries, just go ahead.
