+ Fix some comments concerning LR(0) versus LALR(1).
+
+ Stop equating LR(0) with nondeterminism and LALR(1) with
+ determinism. That is, if all states are consistent, then LR(0)
+ tables are deterministic. On the other hand, LALR(1) tables
+ might be nondeterministic before conflict resolution, and GLR
+ permits LALR(1) tables to remain nondeterministic.

+
+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar
+ translation afterwards. However, other skeletons appear to be
+ fine. glr.c appears to already translate yychar before every
+ use. lalr1.cc does not define yychar and does not document its
+ replacement, yyla, for users. It does provide yyclearin, but
+ that does not manipulate yyla and thus requires no translation
+ update. In lalr1.java, yychar is out of scope during semantic
+ actions.
+ * NEWS (2.5): Document.
+ * data/yacc.c (YYBACKUP): Don't bother translating yychar into
+ yytoken here.
+ (yyparse, yypush_parse): Instead, translate before every use of
+ yytoken, and add comments explaining this approach.
+ * tests/actions.at (Destroying lookahead assigned by semantic
+ action): New test group checking that translation happens before
+ lookahead destructor calls at parser return. Previously,
+ incorrect destructors were called.
+ * tests/conflicts.at (parse.error=verbose and consistent
+ errors): New test group checking that translation happens at
+ syntax error detection before the associated verbose error
+ message and the associated lookahead destructor calls. While
+ the destructor call is fixed by this patch, the verbose error
+ message is currently incorrect due to another bug (see
+ comments in test group), so this is an expected failure for now.
