It is intuitive when you've internalized some of the logic of C-u, and
I originally found it by guessing -- but that's not to say I would've
expected J. Random Emacsuser to necessarily guess it.
For commands where a numeric argument makes sense, they generally take
a numeric argument as a repeat count. For commands where a numeric
argument doesn't make sense, they generally give you an expanded
version of the command. For C-s, this means using a regexp search.
For something like C-x C-f (when you're using ffap), this means
defaulting to whatever "thing" is right at or around the point. For
something like C-h i, which has a default place to look (the system
info dir file), this means prompting you for a different place.
I found this originally by saying, "I want to look at this info file,
but C-h i is defaulting to the wrong place ... maybe an `expanded'
version of this would let me choose the default place".
