[Nek5000-users] write initial condition

[nek5000-users at lists.mcs.anl.gov]

Thanks Mike for the suggestion...

I often achieve this result via:

nekbmpi blah 32
echo 1 > ioinfo

which tells nek to dump on the next step, which, if timing
is good, should be the first.

You're right, however, that we should make it a more certain
thing.   I'll talk with the group here about what would be a
good flag to realize this.
