Subject: [PATCH] After running an action in the debugger, turn it off

When running with "c", there was no problem, but when running with "n"
|
|
|
3f1b01 |
or "s", once the action was executed, it kept executing on the
|
|
|
3f1b01 |
following lines, which wasn't expected. Clearing $action here prevents
|
|
|
3f1b01 |
this unwanted behaviour.
