git-mailinfo - Extracts patch and authorship from a single e-mail message
git-mailinfo [-k] [-u | --encoding=<encoding> | -n] <msg> <patch>
Reading a single e-mail message from the standard input, and writes the commit log message in <msg> file, and the patches in <patch> file. The author name, e-mail and e-mail subject are written out to the standard output to be used by git-am to create a commit. It is usually not necessary to use this command directly. See linkgit:git-am instead.
Usually the program cleans up the Subject: header line to extract the title line for the commit log message, among which (1) remove Re: or re:, (2) leading whitespaces, (3) [ up to ], typically [PATCH], and then prepends "[PATCH] ". This flag forbids this munging, and is most useful when used to read back git format-patch -k output.
The commit log message, author name and author email are taken from the e-mail, and after minimally decoding MIME transfer encoding, re-coded in UTF-8 by transliterating them. This used to be optional but now it is the default.
Note that the patch is always used as-is without charset conversion, even with this flag.
Similar to -u but if the local convention is different from what is specified by i18n.commitencoding, this flag can be used to override it.
Disable all charset re-coding of the metadata.
The commit log message extracted from e-mail, usually except the title line which comes from e-mail Subject.
The patch extracted from e-mail.
