Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Setup.in: added tkinter; rearranged the definition of PYTHONPATH so that the module-specific components are in the section for that module. cursesmodule.c: patched it so it actually works. tkintermodule.c: call Py_AtExit instead of atexit(). signalmodule.c: converted to new naming style; added BGN/END SAVE around pause() call. socketmodule.c: added setblocking() after Tommy Burnette.
