tests/test-parseindex

repo.status: also compare flags for files in the lookup list.

We might be able to do something smarter about this in dirstate.status
for files in normallookup state, but that would require some extra
care to keep backwards compatibility.

#!/bin/sh
#
# 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.
