It looks like this file was simply copied over instead of imported with
gnulib-tool? If I reimport the gnulib/ directory from scratch, we lose it:
[pedro@brno][~/gdb/mygit/src/gdb]
>mv gnulib/ gnulib.org
[pedro@brno][~/gdb/mygit/src/gdb]
>~/src/gnulib/gnulib/gnulib-tool --import --dir=. --lib=libgnu --source-base=gnulib --m4-base=gnulib/m4 --doc-base=doc --tests-base=tests --aux-dir=gnulib/extra --no-libtool --macro-prefix=gl --no-vc-files inttypes memmem
...

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If I pull the "update-copyright" gnulib module in addition, with:
[pedro@brno][~/gdb/mygit/src/gdb]
>~/src/gnulib/gnulib/gnulib-tool --import --dir=. --lib=libgnu --source-base=gnulib --m4-base=gnulib/m4 --doc-base=doc --tests-base=tests --aux-dir=gnulib/extra --no-libtool --macro-prefix=gl --no-vc-files inttypes memmem update-copyright
then we get it back, but, we get an older 2010 version, thus we end up with a non-empty diff, see below.
It doesn't look like we miss anything important for us. I think I'll apply this,
and then update gnulib (using gnulib-tool) to the current upstream version.
Even if we do miss something with the rollback, we're not going to be running
the script in the middle of the year anyway. :-)
Okay in principle?
