+ add examples.
+ (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
+ after printing the error directive so that M4 doesn't report subsequent
+ problems that are induced by this problem.
+ * src/scan-skel.l: Recognize @` digraph outside of directive arguments
+ instead of just in them. Recognize @\n in both places. Both expand to
+ the empty string. Needed by b4_cat.
+ * tests/skeletons.at (Complaining during macro argument expansion):
+ New test case.

+ In impure push mode, don't allow more than one yypstate to be allocated
+ since multiple impure parsers would corrupt yynerrs.
+ * data/push.c (yypstate_allocated): New static global variable
+ initialized to 0.
+ (yypull_parse): If yypstate_new returns 0, don't report it as memory
+ exhaustion if yypstate_allocated is 1, but still return 2.
+ (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
+ already 1. Otherwise, set it to 1.
+ (yypstate_delete): Set it to 0.
+ * tests/push.at (Push Parsing: Multiple impure instances): New test
+ case.
