* generic/tclCmdMZ.c (Tcl_StringObjCmd,STR_IS_INT): Corrected

        inconsistent results of [string is integer] observed on systems
        where sizeof(long) != sizeof(int).  [Bug 718878]
        * tests/string.test: Added tests for Bug 718878.
        * doc/string.n: Clarified that [string is integer] accepts
        32-bit integers.
