* generic/tclInterp.c: Reverted the conversion of [interp] into an
* tests/interp.test: ensemble. Such conversion is not necessary
* tests/nre.test: (or even all that helpful) in the NRE-enabling
of [interp invokehidden], and it has other implications -- including
significant forkage of the 8.5 and 8.6 implementations -- that are
better off avoided if there's no gain.
