	gnats          : ChangeLog field.c field.h getclose.c misc.c 
	                 pr.c query.c query.h 

Log message:
	* pr.c (getFieldHeader): Use xstrndup.
	(write_pr_field): Don't call xmalloc (); instead, be a bit
	smarter about formatting output.  (Can probably remove some
	rather inefficient calls to fprintf() as well.)
	
	* field.c (isConstantFieldValue): New function.
	
	* query.c: Add QueryItem object to hold individual query items;
	this lets us keep around precompiled regexps for constant
	query regexps, instead of recompiling every time.
	(regcmp, regfind): Add pattern buffer argument; only compile
	the regexp into the supplied buffer once.
	
	* misc.c (readLine): Optimize (remove a unnecessary memcpy()).
