* language.h (PRINT_LITERAL_FORM): New macro that takes character 

and decides if it should be printed in literal form or some other
	form, based on it's ASCII value and setting of sevenbit_strings.
	* {c-exp.y, m2-exp.y} (emit_char):  Use new PRINT_LITERAL_FORM
	macro, change indentation style.
	**** start-sanitize-chill ****
	* ch-exp.y (chill_printchar):  Use new PRINT_LITERAL_FORM macro.
	* ch-exp.y (chill_printstr):  First cut at real function instead
	of error stub.
	**** end-sanitize-chill ****

Printing stops early if the number hits print_max; repeat counts
are printed as appropriate. Print ellipses at the end if we
had to stop before printing LENGTH characters, or if FORCE_ELLIPSES.
Note that gdb maintains the length of strings without counting the
terminating null byte, while chill strings are typically written with
an explicit null byte. So we always assume an implied null byte
until gdb is able to maintain non-null terminated strings as well
as null terminated strings (FIXME).
