I'm not sure stderr is particularly more evil than stdout, but whatever :) What you could do is run the help text through a pager only if stdout is a TTY. That allows it to be grepped conveniently, but also browsed easily. But I wouldn't worry about that unless you have at least 3-5 pages of screed - for most programs, just dumping the text to a standard stream is usually enough.
