In v350.3, I changed `current-module-name-resolver'. 

If your code installs a module name resolver, the resolver now needs to
have 1 an 4 arguments, in addition to supporting 3 arguments. More info
is here:

If your code doesn't supply a module name resolver yourself, it may
mean that some library has escaped my attention and needs to be
updated.

In particular, now that I look, I see that stand-alone executables must
be broken, because I forgot about the embedded resolver. I'll fix that.
