Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Rearranged and added comments to object.h, to clarify many things that have taken me "too long" to reverse-engineer over the years. Vastly reduced the nesting level and redundancy of #ifdef-ery. Took a light stab at repairing comments that are no longer true. sys_gettotalrefcount(): Changed to enable under Py_REF_DEBUG. It was enabled under Py_TRACE_REFS, which was much heavier than necessary. sys.gettotalrefcount() is now available in a Py_REF_DEBUG-only build.
