splitter could support ad hoc text entry, to split what it's given on cmd line

[Fred T. Hamster]

like a call like this:

splitter -t "this needs to be split up now, thanks."

ooooh, and it also needs to have a clue about the virtual terminal size to do that effectively without being told the widths.

so we need to do xprop or check env vars for those things.

ha, here's the clue re:
columns and lines xterm for splitter:
# show # lines.
tput lines
# show # columns.
tput cols

ah, also "stty size" works to show lines and columns.
