New mumi am subcommand

[Arun Isaac <arunisaac@systemreboot.net>]

Hi,

The latest mumi CLI (version 0.3.0) comes with a new `mumi am'
subcommand. With this, you can automagically apply the latest patchset
in an issue.

First, set the current issue (say 61036).

$ mumi current 61036

Then, apply the latest patchset using

$ mumi am

You may also apply a patchset of a specific version (say, v3) using

$ mumi am v3

Or, you may apply a patch from a specific e-mail message.  For example,
to apply the patch from the 4th message (message index starts from 0),
run

$ mumi am @4

`mumi am' is a wrapper around `git am'. You can pass in `git am' options
after a `--'. For example, to sign off applied commits,

$ mumi am -- -s

Hope that helps and makes patch review a little less tedious!

I have submitted a patch documenting mumi am and the older compose and
www subcommands in the Guix manual. See

Cheers!
Arun
