Re: [RFD] Place to document magic pathspecs like ":/" and pathspec handling

But I think it is not the best place to keep this documentation.

All true.  In case it was not obvious, I didn't mean to say "Here
you find the information, shut up."  It was "here is a pointer if
you didn't find it, so that you can use it as a starting point to
make a better documentation."

An analogous entity in the world model of Git that appears
everywhere and is not limited to a single command is the revision
set calculus.  Where do we describe it and how do we make it
discoverable?  Can the new way to describe pathspec and pathspec
magic mimic the way it is done for the revisions?
