watchmedo does not work on mac with 0.10.4

[abessiari]

Hi.
0.10.4 does not capture events on mac. 0.10.3 works just fine.
Did anything change that would make 0.10.4 not work on mac?
I have installed 0.10.3 and it works just fine.
With 0.10.4 nothing happens. Problem was produced by running watchmedo.
Thanks.
Python 3.7.9
python -m pip install -U "watchdog[watchmedo]"==0.10.3
python -m pip install -U "watchdog[watchmedo]"==0.10.4
watchmedo shell-command --patterns=".py;.txt" --recursive --command='echo "${watch_src_path}"' .

Fixed by #716. I will release new versions with that important regression fix.
