The tag here should be "hush: ..." The subject should be an action,
such as "Clear do_repeat flag after running commands".

What is "it" here? Please add a few more sentences describing why you
want to change this. For example, you could note that do_repeat is a
file-level variable which is used by get_user_input to signal when a
command should be repeated. Though, I wonder why we don't set the flags
in the first place...

Multi-line comments should start with a blank line.

Can you add a test case for this?
