[Libguestfs] [PATCH nbdkit v2 0/6] plugins: Implement magic config key.

[Richard W.M. Jones]

v1 was here:

  https://www.redhat.com/archives/libguestfs/2018-September/msg00024.html

v2:

 - As discussed in the patch review, tighten up the characters
   permitted in keys.

 - Update documentation to note that relative paths can be made
   safe by prefixing with ./ and absolute paths do not need any
   extra steps.

 - I pushed patch 1/6 from the v1 series since it was just a trivial
   comment update.

Rich.
