Oh, sorry about this, I thought the options I have set don't affect the 
style in particular, but you're right. I attach a more complete .zshrc 
with the options I have set as well.

Great find! Although that workaround did not work for me, the one that 
did (a more ugly one, but...) was to simply remove the call to _messages:
functions[_mkdir]="${functions[_mkdir]:s/ || _message 'name of directory'/}"
And now it works great. Thank you!
