* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
values, changed to not be an error, but behave like the special
value -1 (copy all, default).
* tests/iocmd.test (iocmd-15.{12,13}): Removed.
* tests/io.test (io-52.5{,a,b}): Reverted last change, added
* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
meaning of -1, added two more testcases for other negative values,
and input wrapped to negative.
