Be less misleading in errors, data.c

src/ChangeLog addition:

2015-05-09  Aidan Kehoe  <kehoea@parhasard.net>

	* data.c (Flogand):
	* data.c (Flogior):
	* data.c (Frem):
	* data.c (Flsh):
	Give less misleading errors in all these functions, e.g. supplying
	#'integer-char-or-marker as the predicate on wrong-type-argument,
	when float would not be accepted.
