Also apply filters so that public routines only pass documented flag values down to lower level routines. * generic/tclVar.c (CallVarTraces): The setting of the TCL_INTERP_DESTROYED flag is now done entirely within the CallVarTraces routine, the only place it can be done right.

| | | | | | | | | supplied by Mo DeJong to fix [Bug 1516109]. Backport from Tcl 8.5. Mo's description: Clear the TCL_ENCODING_END flag when end bytes are written. This fix keep this method from writing escape bytes for an encoding like iso2022-jp multiple times when the escape byte overlap with the end of the IO buffer. * tests/io.test: Add test case for escape byte overlap case.
* Backport to 8.4 (Don Porter's work).andreas_kupries2006-12-051-1/+3
| | | | | | | | | | | | When no requirements are supplied to a [package require $pkg] and [package unknown] is invoked to find a satisfying package, pass the requirement argument "0-" (which means all versions are acceptable). This permits a registered [package unknown] command to call [package vsatisfies $testVersion {*}$args] without any special handling of the empty $args case. This fixes/avoids a bug in [::tcl::tm::UnknownHandler] that was causing old TM versions to be provided in preference to newer TM versions. Thanks to Julian Noble for discovering the issue.
