Changes 8.4.13:
* Win NT/XP: unicode console support taken back out. * ${prefix}/share addition to ::tcl_pkgPath undone. * Warning message for packages with incorrect index scripts silenced. * Correct syntax error in configure script (bash 3.1 exposes it). * Tk incompatibilities with SCIM resolved. * Improved [file writable] support of Windows conventions. * Tcl_GetIndexFromObj() support for exact matching of empty key. * Tk Portuguese localization support (pt.msg). * Tk more robust when X server does not recognize color name "Black". * Tk_PhotoPutBlock() performance improvement. * [lsearch -start $pastEnd] no longer finds match at end of list. * Correct [expr abs($LONG_MIN)] result. * Correct [string range] failures on some strings containing \x00. * TCL_EVAL_GLOBAL and [uplevel 0] agreement when traces or [unknown] active. * Corrections to context of auto-loading the target of an interp alias. * Corrected some interference between enter and enterstep traces. * Correct [$img configure -data] failure to change X display. * Tk_GetBitmapFromData() thread safety. * Crashes in [grid] for some invalid index arguments. * Crash when all content of a [text] is elided. * Crash in [$text edit undo/redo]. * Crash in animated GIF display with variable frame size. * Crash related to pipe usage in thread-enabled Tcl on Windows. * Crash when [$text dump -command] changes contents while dumping. * Crash reading utf-8 when multibyte char spans multiple buffers at EOF. * Several finalization crashes corrected.
