Thanks, applied with small changes (see below.)

I adjusted the commit log to follow GNU conventions.

Passing a version string is quite inelegant and fragile, so I changed
‘autoconf-wrapper’ to instead take a package object.

So:

  (autoconf-wrapper)

returns a wrapper for the default ‘autoconf’ package, and:

  (autoconf-wrapper autoconf-2.68)

returns a wrapper for that particular version.

Thanks,
Ludo’.
