Details:

Octave's pause function doesn't respond to key presses when executed without
arguments. 

Rather, it simply pauses the program indefinitely, with no way to resume
program execution. I discovered this while working through Andrew Ng's ML
course using Octave, where I had to simply comment out the pause commands in
order to run the scripts. 

Other test cases:

1. "r = [1;2;3]; pause; f=[3;4;5]" in the repl will freeze indefinitely

2. "r = [1;2;3]; pause(0.05); f=[3;4;5]" will freeze until key press if the
time determined by the argument has passed. Else, it will not respond to key
press.

3. using "pause (0.05)" in Ng's ML scripts will work as expected.

By key press, I hold the same definition defined in the documentation.
