Note doc/valgrind-tests.texi doesn't mention the configure option, so I'm thinking we should leave the auto enablement as is and change the HELP_STRING like: s/enable/disable/ ? thanks, Pádraig.

Now locale_charset() is not usually separately available on GNU/Linux but it can be on FreeBSD for example: http://permalink.gmane.org/gmane.comp.version-control.git/243879 I'm guessing that gnulib was always updated with the latest version, and so for this smallish function it was simpler and arguably better for gnulib using programs to consume it from there. I'd accept a patch that favored the separated version. thanks, Pádraig.
