Sorry about posting my own follow-up but it seems that the
regexp-opt
library does exist but is simply not being autoloaded for use by
make-mode.el. I know how to kludge a fix for this locally in my own
.emacs but what is the proper fix?
`regexp-opt' has an autoload cookie:
C-h f regexp-opt
`regexp-opt' is an autoloaded Lisp function
-- autoloads from "regexp-opt"
Documentation:
Return a regexp to match a string in STRINGS.
