* generic/tclUtil.c:
* generic/tclCmdMZ.c: Replaced "string icompare/iequal" with
-nocase and -length switches to "string compare/equal".  Added a
-nocase option to "string map".  Changed index syntax to allow
integer or end?-integer? instead of a full expression.  This is
much simpler with safeTcl scripts since it avoids double
substitution issues.
