This is the filter for rewriting the commit's parent list.
It will receive the parent string on stdin and shall output
the new parent string on stdout. The parent string is in
- a format accepted by linkgit:git-commit-tree[1]: empty for

the initial commit, "-p parent" for a normal commit and
"-p parent1 -p parent2 -p parent3 ..." for a merge commit.
--commit-filter <command>::
This is the filter for performing the commit.
If this filter is specified, it will be called instead of the
- linkgit:git-commit-tree[1] command, with arguments of the form

"<TREE_ID> [-p <PARENT_COMMIT_ID>]..." and the log message on
stdin. The commit id is expected on stdout.

As a special extension, the commit filter may emit multiple

You can use the 'map' convenience function in this filter, and other
convenience functions, too. For example, calling 'skip_commit "$@"'
will leave out the current commit (but not its changes! If you want
-that, use linkgit:git-rebase[1] instead).

that choice by this parameter.
