initial tabulation in the actual code.
Fix stylistic issues: avoid the , operator.
Add extexi mark-up.

forward them to errlab1.
* tests/c++.at (Syntax error as exception): Check support for
syntax exceptions raised by the scanner.
* NEWS, doc/bison.texinfo: Document it.
* doc/bison.texinfo (Locations Overview): Rename node to...
(Locations): ... this, which is its section name. Update menus to
match that and not to use the title `Tracking Locations', which is
a different section.
(cherry picked from commit 8348436580)
* doc/bison.texinfo (Locations): Rename node to...
(Tracking Locations): ... this, which is its section name, and
update all cross references. The trouble is that there is another
node about locations. Its section name is `Locations', which was
easily confused with the node name of this node. Moreover, its
node name is `Locations Overview', which was mistakenly used to
label some cross references to this node.

named references are experimental as we've already stated in NEWS.

accept a new parameter for telling the caller whether true is

warnings, and continue to use warn_at for all other warnings. Let
them check whether the warnings are enabled.
* tests/local.at (AT_BISON_CHECK): Update documentation.
(AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
disable all warnings exercised in the test suite.
