The <info>%command.name%</info> command squashes all commits of a pull-request:

    <info>\$ gush %command.name% 12</info>

Make sure you are the pull-requests\\'s source-branch repository owner
or have been granted push access to the repository.

Note: This will squash all commits in the pull-request and (when a local branch exists with
the same name) sync your local source branch with the squashed version.
You can skip this sync-process using the <comment>--no-local-sync</> option.
