Thanks!  The changes LGTM.  I will suggest a micro-improvement not
related to this patch since it was there from before:

I was confused whether the #t was the "else" clause for the "if"
expression until I realized it didn't have one.

Could you turn this into a (when (file-exists? ...) (for-each ...))
while at it?  It also makes the (begin ...) redundant.
