tests: check that 'log --line-range' follows uncommitted changes
The reason we start walking revisions from the working directory (None
revision) in logcmdutil.getlinerangerevs() is because we can follow
uncommitted changes. Adding a test to illustrate this based on an
uncommitted rename as there was none before. This helps understand the
fix in next changeset.
