compute inveclosure only if actually needed.

2004-12-31  Paolo Bonzini  <bonzini@gnu.org>

	* regcomp.c (calc_inveclosure): Return reg_errcode_t.
	Initialize the node sets in dfa->inveclosures.
	(analyze): Initialize inveclosures only if it is needed.
	Check errors from calc_inveclosure.
	* regex_internal.c (re_dfa_add_node): Do not initialize
	the inveclosure node set.
	* regexec.c (re_search_internal): If nmatch includes unused
	subexpressions, reset them to { rm_so: -1, rm_eo: -1 } here.
	Limit to preg->re_nsubs the nmatch that is passed to set_regs.
	(set_regs): Remove the real_nmatch variable, the nmatch
	parameter now is <= preg->re_nsubs.
