Parsing status occasionally wrong

[xkortex]

I'm noticing under some conditions, dps (docker-pretty-ps) reports containers as running when they are exited. This appears to be an issue with revised_line_split[4] on line 227.

Here's my output when I add this line to _clean_status(val)

    print('STATUS: {} [{}]'.format(val, val.lower().strip()))

STATUS:  Exited (0) About an hour ago [exited (0) about an hour ago]
STATUS:  Exited (1) About an hour ago [exited (1) about an hour ago]
STATUS: Created [created]
STATUS: Exited (127) 4 days ago [exited (127) 4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS:  4 days ago [4 days ago]
STATUS: Exited (1) 4 days ago [exited (1) 4 days ago]
STATUS: Exited (1) 4 days ago [exited (1) 4 days ago]
STATUS: Exited (1) 4 days ago [exited (1) 4 days ago]

...(truncated)...
Total containers:	33
Total running:		6

Those 6 running appear to be coming from the failure to split the output properly. Here's some sample output that causes the splitting to fail.

Oof. Was planning to rewrite this using go templating. I'll try and use this as a use case for that. If you've got a PR in the meantime I'd be happy to bake it in.
