    And some of those uses are quite weird, BTW:

     - In erc/erc.el:
	(separator (make-string erc-fill-column (string-to-char "=")))
	(make-string (length x) (string-to-char "b"))

     - In progmodes/fortran.el:
	(or (equal char (string-to-char " "))

    Aren't these redundant? (I don't think the unibyte/multibyte issue is
    relevant in any of them...)

Please feel free to simplify them.
