mq: don't mention qinit as a "common task" Without -c, it is a no-op (the queue is implicitly initialized by all relevant commands if needed), and queue repositories with -c are an advanced usage of mq, and not otherwise required.

# revlog.parseindex must be able to parse the index file even if
# an index entry is split between two 64k blocks.  The ideal test
# would be to create an index file with inline data where
# 64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
# the size of an index entry) and with an index entry starting right
# before the 64k block boundary, and try to read it.
#
# We approximate that by reducing the read buffer to 1 byte.
