[Message part 1 (text/plain, inline)]
With is rather like if ... else .... so maybe:
When FILE is '-', read standard input. If no FILE is given, with -r, recursively search the working directory instead, else read standard input. With fewer than two FILEs, assume -h. Exit status is 0 if any line is selected, 1 otherwise; if any error occurs and -q is not given, the exit status is 2.

Thanks for the suggestions. I went with Paul's (keeping it concise is
important), so --help now prints this:
When FILE is '-', read standard input. If no FILE is given, read standard
input, but with -r, recursively search the working directory instead. With
fewer than two FILEs, assume -h. Exit status is 0 if any line is selected,
1 otherwise; if any error occurs and -q is not given, the exit status is 2.
Here's the commit:

Marking this as done.
