--diff-algorithm=(patience|minimal|histogram|myers)

Choose a diff algorithm. The variants are as follows:

default
myers

The basic greedy diff algorithm. Currently, this is the default.

minimal

Spend extra time to make sure the smallest possible diff is produced.

patience

Use "patience diff" algorithm when generating patches.

histogram

This algorithm extends the patience algorithm to "support low-occurrence common elements".

For instance, if you configured the diff.algorithm variable to a non-default value and want to use the default one, then you have to use --diff-algorithm=default option.
