am.keepcr:: If true, linkgit:git-am[1] will call linkgit:git-mailsplit[1] for patches in mbox format with parameter `--keep-cr`. In this case linkgit:git-mailsplit[1] will not remove `\r` from lines ending with `\r\n`. Can be overridden by giving `--no-keep-cr` from the command line. am.threeWay:: By default, linkgit:git-am[1] will fail if the patch does not apply cleanly. When set to true, this setting tells linkgit:git-am[1] to fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to and we have those blobs available locally (equivalent to giving the `--3way` option from the command line). Defaults to `false`. am.messageId:: Add a `Message-ID` trailer based on the email header to the commit when using linkgit:git-am[1] (see linkgit:git-interpret-trailers[1]). See also the `--message-id` and `--no-message-id` options.
