Yes. At the beginning, I placed 'int recurse' in that struct. However, I
thought that this struct does not say anything about selecting files,
but it says how to grep files (invert, count, fixed [string], binary
etc.). Most of opts (if not all) are used in grep.c, not builtin-grep.c.

Yeah, I found out that...

Actually, this is what I wanted: Do not descend to subdirectories of
selected directories. After a while, I think this action should be
called "read [files in that directory]", not "skip".
