* generic/tclTest.c (TestconcatobjCmd):
* generic/tclUtil.c (Tcl_ConcatObj):
* tests/util.test (util-4.7):
fix [Bug 1447328]; the original "fix" turned Tcl_ConcatObj() into
a hairy monster. This was exposed by [Bug 2055782]. Additionally,
Tcl_ConcatObj could corrupt its input under certain conditions!
*** NASTY BUG FIXED ***
