For very long command lines it would be better if you could click a
button to edit the text in a bigger window (similar to MS Access Zoom)
or something similar. E.g. I'm compiling java, I have to specify the
classpath of rt.jar and tools.jar, and the class name of the compiler,
and the classpath to pass to the compiler - rt.jar (don't know why I
have to specify it again - I'm using mysaifu) and the file's working
directory, and lastly the file's filename.
