It might be useful to expose "depth" concept described in
svn_wc.h to command line option.

    The WebDAV concept of "depth" may be useful in understanding the
    motivation behind this. Suppose we're getting the status of
    directory D. The three depth levels would mean

       depth 0: D itself (just the named directory)
       depth 1: D and its immediate children (D + its entries)
       depth Infinity: D and all its descendants (full recursion)

Then user will have full control over how the given command
should recurse. Recursive and nonrecursive will be an alias
to one of them depending on the nature of the command as you
described. I think I'll just type svn revert . * instead of
svn --depth 1 revert, though. :-)
