Many commands have flags to recurse into submodules, which is named
--recurse-submodules. The diff family also has a submodule recursion flag,
but that is named differently. Add a synonym --recurse-submodules, which
means the same as the --submodule flag, such that across all git commands
supporting submodules we have the --recurse-submodules flag available.

Specify how differences in submodules are shown. When specifying
- `--submodule=short` the 'short' format is used. This format just
- shows the names of the commits at the beginning and end of the range.
- When `--submodule` or `--submodule=log` is specified, the 'log'
- format is used. This format lists the commits in the range like
- linkgit:git-submodule[1] `summary` does. When `--submodule=diff`
- is specified, the 'diff' format is used. This format shows an
- inline diff of the changes in the submodule contents between the
- commit range. Defaults to `diff.submodule` or the 'short' format
- if the config option is unset.
