There is no hard limit at the data structure level.

git-commit-tree has a hard limit of accepting 16 parents.  git-blame has
the same 16-parent limit while following the history (but the one in
'next' has lifted the latter limitation).

But that is purely academic.  Anybody who does an octopus with more than 8
legs should get his head examined ;-).
