Hmm... this is annoying: the bytecompiler failed to inline cl-minusp
because it was not yet byte-compiled when we byte-compiled ibuffer.el.
I.e. if you recompile ibuffer.el at the end, it will properly eliminate
cl-minusp.

This is because the byte-optimizer does not know how to inline
a dynamically scoped interpreted function into a lexically scoped
function, or vice-versa.  So the inlining can fail.

Once the inlinable function is byte-compiled, the problem disappear,
because we know how to inline it in any context.
