We try to have a clean-as-you-go policy. Try to improve bits and bobs while maintaining the code base as a whole. While (IMO) a one-liner here and there is fine, it can quickly spiral out of control. I usually keep an improvements commit at the start of my branch which I `--amend` to while picking away at the task. If the commit gets too big I submit it separately, to be reviewed in isolation.
