commit: add a way to return more information from the chunkselector Before this patch, the chunkselector for record or crecord was used to return the list of hunks that were selected by the user. The goal of this series is to reintroduce the toggle amend feature for crecord. To do so, we need to be able to return more than just the selected hunks from the chunkselector but also the information: is amend mode toggled. This patch adds a new return value for chunkselectors that will be used to implement the toggle amend feature in crecord.
