[O] Limit on length of babel block #+name: value?

[John Hendy]

I was just completely baffled for about 5-10 straight minutes as to
why my block was not producing a  results section with my generated
graphics file from an R block.

I kept double checking my header options one by one despite having
simply copied/pasted/modified it from a previous working block. Turns
out it appears that #+name has a character limit!

This (on Org-mode version 8.0.2 (release_8.0.2-65-g1e32d7)), doesn't work:

#+name: improvement-treatment

It appears the name can be 20 characters long (the above is 21).

Is this by design or something I accidentally uncovered? Forgive me if
it's come up before or is documented. I did a couple searches but
didn't see it.


Thanks,
John
