The key is that bash doesn't do quote removal on the `string' part of the
"${param/pat/string}" expansion.  The double quotes are key; quote removal
happens when the expansion is unquoted.

Double quotes are supposed to inhibit quote removal, but bash's hybrid
behavior of allowing quotes to escape characters but not removing them
is biting us here.
