[John Ferlan]

Commit id 1bff5bbe25eb7a7e7a4e0067c4ca7cbc1cb34999 accidentally
reverted .gnulib back to d6397dde2e127e246e3eeb5254a21f42cac783c8
which was two updates ago.

Update to the latest 68df637b5f1b5c10370f6981d2a43a5cf74368df
which includes three changes since the previous fetch of
cdbf3d385a32ff904c96f20c26f3470bd8345248.

> autoupdate
> hard-locale: simplify by removing hard-locale.m4
> gnulib-tool: limit line length for git send-email

 Pushing under this I know fixes some previous build breaking issue
 and of course it's a .gnulib maint, so that's reason #2.
