Summary: unnecessary string copy in INST_CONCAT1

Initial Comment:
INST_CONCAT1 will always copy the first item; this is
not necessary whenever it is unshared and its
string-rep has enough room for the appending. This
should be fixed by either duplicating code from
AppendUtfToUtfRep (in tclStringObj.c), or calling it.
