* generic/tclIO.c (Tcl_GetChannelHandle): [Bug 2826248]: Do not crash
* generic/tclPipe.c (FileForRedirect): for getHandleProc == NULL, this
is allowed. Provide a nice error message in the bypass area. Updated
caller to check the bypass for a mesage. Bug reported by Andy
Sonnenburg <andy22286@users.sourceforge.net>. Backported from CVS
head.
