Joel E. Denny 9874460819 maint: run "make update-copyright" 
But first...
* .x-update-copyright (^data/m4sugar/): Add, because these
files are from Autoconf.

Joel E. Denny 915becaa5d maint: make update-b4-copyright easier to use 
* build-aux/update-b4-copyright: In warnings, report line
numbers rather than character positions.
* cfg.mk (update-copyright-local): Set to update-b4-copyright so
that update-copyright runs it.
* gnulib: Update.
(cherry picked from commit a1a9422d4a)

Joel E. Denny ae50972393 maint: clean up update-b4-copyright code 
* build-aux/update-b4-copyright: Do not accept 2-digit
UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
Don't accept a `[' in a b4_copyright argument.
Format code more consistently.
Don't assume b4*copyright never occurs.
(cherry picked from commit 0b61a8ec18)

Joel E. Denny 50bcb22c4c maint: automate annual package-wide copyright-year update. 
* .x-update-copyright: New.
* Makefile.am (EXTRA_DIST): Remove maint.mk.

update-copyright.  Remove gnumakefile, which is implied by
maintainer-makefile.
* cfg.mk (bootstrap-tools): Copy from old maint.mk.
* gnulib: Update.
* maint.mk: Remove, now copied from gnulib.

update-copyright can recognize it.

* src/print_graph.h: Likewise.
* src/gram.c: Add missing comma in copyright statement.

Joel E. Denny cfc9e431c3 Fix "make distcheck".

of just calc.stamp.

Joel E. Denny 42f8609bbd Pacify "gcc -Wunused" for the input function from Flex. 
Reported by Alex Rozenman.  This warning shows up with gcc-4.3.0
and later.
* src/scan-code.l: Add "%option noinput", which I cannot find in
the Flex manual, but which Flex has supported since at least as
far back as 2.5.4.  However, if any of our developers still use
Flex 2.5.4, they'll need to stop configuring with
--enable-gcc-warnings because "%option noinput" didn't work
correctly until Flex 2.5.6.
* src/scan-gram.l: Likewise.
* src/scan-skel.l: Likewise.
