testing a cheaper(?) INST_START_COMMAND
Test for Bug 1884496 (not buggy on trunk).
fix for consecutive ISC (produced by [while 1 {...})
better comments
merge trunk

Put back TclBackgroundException in internal stub table, so extensions using this, compiled against 8.5 headers still run in Tcl 8.6.
If TCL_NO_DEPRECATED is defined, make sure that TIP #139 functions all are taken from the public stub table, even if the inclusion is through tclInt.h.

forgot two #undef's
merge trunk
remove some EXTERN and CONST usages in tclWinPort.h
More flexible search for win32 tclConfig.sh, backported from TEA (not actually used in Tcl, only for Tk)
