branchcache: gather new obsolete revision in a set This is part of a series to more clearly split the update in two step. This will allow us to introduce a fast path during update in a future changeset.

import sys

for line in sys.stdin:
    if line.lower() in ("message-id: \n", "in-reply-to: \n"):
        line = line[:-2]
    print(line, end="")
