diff-algorithm-option

--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.
