Fix an issue with confirmation to close terminal.

Sometimes, it happens that closing terminal with mouse/keyboard
confirmation dialog appears (no matter if it was graphical or the one
build on top of urxvt overlay).

The culprit was with lines origin from `ps` command, which wasn't
correctly split, but, what is more important, wasn't properly trimmed.
This commit fixing the issue by removing whitespace from both ends of
the string and splitting using space character rather, than regexp, and
second, be sure to chop off all the whitespace characters before
splitting line and after splitting process name and its arguments.
