Unable to read json file in windows git bash

[meblum]

fx does not detect that the file descriptor is a terminal when using git bash on windows, so it always expects input from stdin. When calling fx with no argument, it just remains hanging instead of returning with usage info.
When a file is passed as an argument, it interprets it as a function.

Seems that the problem is only on newer versions of git bash.
