In rrd_create.c, there are a few places where the file version will
be marked RRD_VERSION (the default is version 1, but once arguments
specified in create request new features, the version tag is rewritten).
If you change the default to RRD_VERSION, please remove these references

(they will no longer have a purpose).

If you want to preserve the creation of version 1 files, you will need
to add a flag to create and then condition the fwrite on the presences
of this flag.
