comparison Python/import.c @ 36065:ea083efdc96c legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines, simplifies a lot of error handling code, and fixes many memory leaks.
