* data/Makefile.am: Update copyright date.

Browse Source 
* data/push.c (yypull_parse): Report memory exhaustion and return 2 if
yypstate_new returns NULL.
(yypstate_new): Return NULL if malloc does.
* src/reader.c (packgram): Move translation of rule actions from the
beginning of packgram to...
(check_and_convert_grammar): ... here right before packgram is invoked
so it's easier to write more complete comments, and remove redundant
code.
