There is a small problem:

                                                ===
`pos' is not defined.

I can't deduce a useful value for it from the context.  So it seems
it should be removed from isearch.el, and the argument `pos' of
subregexp-context-p be changed to optional.  Is it what you intended?

PS: I noticed this problem only during testing.  Even if the byte
compiler generated a warning message, it remains unnoticed among other
numerous similar warnings.  There is an urgent need to get rid of all
warnings that refer to a valid use of free variables, and to find and
fix true bugs reported by remaining warnings before the next release.
