[c31ca233ca] Fix TclGetsObjBinary() so that each [gets] rediscovers whether
a nonblocking channel is blocked.
Update Unicode tables to Unicode 7.0
Repair buffer indexing error in Tcl_ReadRaw() exposed by iogt-6.0 and valgrind.
[7368d225a6] Extend the auto-cleanup of zero ref count values passed in
to the Tcl_*SetVar*() family of routines to cover the missing case where
the flags value of TCL_APPEND_VALUE is passed in alone.
*** POTENTIAL INCOMAPTIBILITY***
dup test name
Starting with Unicode 6.3, the mongolian vowel separator (U+180e) is no longer a whitespace, but for Tcl it still is. 
"NEL/Next Line" (U+0085) should have been a Unicode whitespace, but never was in Tcl. This is corrected in Tcl 8.6, but for legacy reasons not in Tcl 8.5.
Update documentation accordingly, and extend test-cases for Unicode 7 compliance.
Assert an equality test, not an assignment.
