Subject: Corrects reported bug, but makes many tests fail.  Something subtle
 about what we should expect when recording the line of a command that isn't
 known until runtime.

Subject: [16828b3744] [vwait] *must* successfully undo its variable trace, or
 else it risks corrupting memory.  Namespace teardown complexities were giving
 the traces an opportunity to survive.  Added another (arguably better)
 Tcl_UntraceVar() call to be sure we avoid this problem.
