Commit tool: autoinc (Auto-includes) shall be ignored for merge
THg (v1.1.8) has in user manual ch. 4.5.10. Configurable Commit ‣ Auto Commit List: Comma separated list of files that are automatically included in every commit. Intended for use only as a repository setting.
However, using that prevents merge. Workaround: clear the Auto-includes field in Commit view advanced mode, then commit merge.
Commit should not specify the autoinc list when committing a merge.
