[MITgcm-support] runtime error

[Patrick Heimbach]

Oops, I just did injustice in claiming "no doc on this".
Many of the MNC parameters are actually documented in the manual,
see section 7.2
http://mitgcm.org/r2_web_testing/latest/online_documents/node259.html
(but not complete, the MNC_MAX_FID is missing).
-p.
