Subject: [PATCH] add--interactive: respect diff.algorithm
When staging hunks interactively it is sometimes useful to use an
alternative diff algorithm which splits the changes into hunks in a more
logical manner. This is not possible because the plumbing commands
called by add--interactive ignore the "diff.algorithm" configuration
option (as they should).
Since add--interactive is a porcelain command it should respect this
configuration variable. To do this, make it read diff.algorithm and
pass its value to the underlying diff-index and diff-files invocations.
At this point, do not add options to "git add", "git reset" or "git
checkout" (all of which can call git-add--interactive). If a user
wants to override the value on the command line they can use:
git -c diff.algorithm=$ALGO ...
