This module too was causing horizontal scrolling because of the shell command. I managed to discover that you only need to specify 'png:' *or* "foo.png", not both, which trimmed off enough characters.
Also, I improved the docs for my functions.
It turns out that for urxvt, and most terminal, apparently, once you give a '-e' option, that's it.
They will not interpret anything after that as anything but input for /bin/sh, so if you wanted to go 'runInTerm "'screen -r session' -title IRC"',
you were SOL - the -title would not be seen by urxvt. This, needless to say, is bad, since then you can't do stuff like set the title which means
various hooks and extensions are helpless. This patch adds an extra options argument which is inserted *before* the -e. If you want the old behaivour,
you can just go 'runInTerm "" "executable"', but now if you need to do something extra, 'runInTerm "-title mutt" "mutt"' works fine.
This patch also updates callers.
