FROM is a regexp and TO is the replacement to use.
FILES describes the files, as in `fileloop-initialize'.
CASE-FOLD can be t, nil, or `default':
if it is nil, matching of FROM is case-sensitive.
if it is t, matching of FROM is case-insensitive, except
when `search-upper-case' is non-nil and FROM includes
upper-case letters.
if it is `default', the function uses the value of
`case-fold-search' instead.
DELIMITED if non-nil means replace only word-delimited matches."
;; FIXME: Not sure how the delimited-flag interacts with the regexp-flag in
;; `perform-replace', so I just try to mimic the old code.
