Improving error message in explain_cannot_find_well_typed_abstraction:
make head bound variables distinct from the variables in environment,
so that the naming scheme is the same when, say, printing "fun x:B => foo x"
in environment "x:A" (main error with explicit "fun") and when
printing (secondary error in the "reason" message) "foo x" in
environment "x:A, x:B" (i.e. with "fun" discharged in environment).
