[CRIU] [PATCH] Issue 329: Reducing scope of variables in action-scripts.c

[Andrei Vagin]

you need to move "Issue 329" from the subject to the body,
so the subject will look like this:
action-scripts: Reducing scope of variables

I would like to see a full link to the issue, it is more convinient if
we read the history from a terminal.
