hook: add support for disabling the shell to native command translation
I think having it on by default is the right thing to do, but this is an escape
hatch if someone has a command that shouldn't be mangled. The inspiration is
the priority prefix. The translation does nothing on non Windows platforms, so
the default value is selected to avoid printing a useless note by default.
# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
