diff Python/ceval.c @ 1016:a41e3ba5b47d legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add some debugging features if DEBUG defined (fetch the filename as a string so I can see it with dbx, and set f_lineno); call abort() when detecting an "undetected" error.
