+ doc: finish splitting apart the manual's Decl Summary section.
+ Suggested by Akim Demaille at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>.
+ * doc/bison.texinfo (Decl Summary): Extract most of the %define
+ entry into...
+ (%define Summary): ... this new subsection, and update all
+ cross-references. For readability of the patches, rewriting of
+ the text so it makes sense as a separate subsection will come in a
+ later patch. Moreover, the majority of the text describing the
+ various new LR features should likely move to another new section
+ somewhere.

+
+ doc: clean up naming of various Bison files.
+ The Bison manual's names for various files associated with a Bison
+ parser has devolved into inconsistency. This patch makes the
+ naming consistent for the most important files. First, it chooses
+ "grammar file" over "input file". The former appears to be more
+ traditional in the Bison manual, and Bison has other input
+ files (skeletons). Second, it chooses "parser implementation
+ file" over names like "parser file", "parser source file", "parser
+ source code file", and "parser output file". The new name makes
+ it clearer where Bison generates the main parser implementation,
+ and it is easily distinguishable from "parser header file".
+ * doc/bison.texinfo: Implement throughout.

+
+ doc: give credit to more of Bison's developers.
+ * doc/bison.texinfo (Introduction): Don't imply that only Robert
+ Corbett, Richard Stallman, and Wilfred Hansen have contributed to
+ Bison. However, I don't have time to write a full history, so
+ just point readers to THANKS and ChangeLog.

+
+ doc: document experimental features better.
+ * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
+ LR(1) are experimental. Mention Java. Normally experimental
+ features probably shouldn't be mentioned in the introduction.
+ However, if Bison's limitations to LALR(1), C, and C++ are so
+ important that they should be mentioned here, then it's important
+ to point out that Bison is beginning to escape those limitations.
+ Moreover, these particular experimental features have very little
+ chance of being removed.
+ * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
+ experimental.

+
+ Do not allow identifiers that start with a dash.
+ This cleans up our previous fixes for a bug whereby Bison
+ discarded `.field' in `$-1.field'. The previous fixes were less
+ restrictive about where a dash could appear in an identifier, but
+ the restrictions were hard to explain. That bug was reported and
+ this final fix was originally suggested by Paul Hilfinger. This
+ also fixes a remaining bug reported by Paul Eggert whereby Bison
+ parses `%token ID -123' as `%token ID - 123' and handles `-' as an
+ identifier. Now, `-' cannot be an identifier. Discussed in
+ threads beginning at
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
+ * NEWS (2.5): Update entry describing the dash extension to
+ grammar symbol names. Also, move that entry before the named
+ references entry because the latter mentions the former.
+ * doc/bison.texinfo (Symbol): Update documentation for symbol
+ names. As suggested by Paul Eggert, mention the effect of periods
+ and dashes on named references.
+ (Decl Summary): Update documentation for unquoted %define values,
+ which, as a side effect, can no longer start with dashes either.
+ * src/scan-code.l (id): Implement.
+ * src/scan-gram.l (id): Implement.
+ * tests/actions.at (Exotic Dollars): Extend test group to exercise
+ bug reported by Paul Hilfinger.
+ * tests/input.at (Symbols): Update test group, and extend to
+ exercise bug reported by Paul Eggert.
+ * tests/named-refs.at (Stray symbols in brackets): Update test
+ group.
+ ($ or @ followed by . or -): Likewise.
+ * tests/regression.at (Invalid inputs): Likewise.
