[PATCH 0/4] xdiff: reduce the size of a couple of arrays

[Phillip Wood <phillip.wood123@gmail.com>]

From: Phillip Wood <phillip.wood@dunelm.org.uk>

When the myers algorithm is selected the input files are pre-processed
to remove any common prefix and suffix. There are a couple of places
where we allocate arrays large enough to hold the whole file when
they only need to be big enough to hold the remaining lines after the
common prefix and suffix have been removed. This series adjusts those
allocations to avoid allocating space for the common lines.

These patches are based on 'en/xdiff-cleanup-3'
