I just found this page which explains the deal with the dots in
directory names:

https://developer.apple.com/library/archive/technotes/tn2206/_index.html

search for "period".

It also explains why you need to put code in certain directories. I
don't know why that page has been so hard to find.

Anyway, I guess we do need to change the install location so it
doesn't have the dots. It shouldn't really matter for the application
bundle since you can't have multiple versions of Emacs installed in
one bundle (without some hardcore messing around like the
emacsformacosx.com builds).
