Log message:
	* src/parse-gram.y (CHARACTER): Remove unused token.
	All uses removed.
	
	* src/scan-gram.l: Remove stack option.  We no longer use the
	stack, since the stack was never deeper than 1; instead, use the
	new auto var c_context to record the stacked value.
	
	Remove nounput option.  At an unexpected end of file, we now unput
	the minimal input necessary to end cleanly; this simplifies the
	code.
	
	Avoid unbounded token sizes where this is easy.
	
	(unexpected_end_of_file): New function.
	Use it to systematize the error message on unexpected EOF.
	(last-string): Now auto, not static.
	(YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
	(scanner_last_string_free): Remove; not used.
	(percent_percent_count): Move decl to just before use.
	(SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
	not the (never otherwised-used) CHARACTER.
