Ah, I knew i forgot something. It changed a bit in 1.6.0. The a -> A and
the trailing dot after the strategies.

Yes, touch /usr/local/bin/git-merge-clint and +x it:
% git merge -s ''
Could not find merge strategy ''.
Available strategies are: file octopus ours recursive resolve subtree.
Available custom strategies are: mikachu.
%

It is also "future-proofed" against something like this, same as the sed
script:
% git merge -s ''
Could not find merge strategy ''.
Available strategies are: file octopus ours recursive resolve subtree.
Available custom strategies are: mikachu.

Make sure you spell strategy names correctly.

So it should be
merge_strategies_cache=(${(s: :)${${${${(f)"$(git merge -s ''
2>&1)"}[(r)[Aa]vailable strategies are: *,(r)]}%%.}##*: }})
