Indexes contains one entry per coordinate, even if there are indexes that index multiple coordinates. This deduplicates the entries, but the format is not quite clear.

  • [x] follow-up to #6795
  • [x] Tests added
  • [x] User visible changes (including notable bug fixes) are documented in whats-new.rst

The formatting options we were able to come up with: 1. separate with just newlines (see e29aeb9085bc677e16dabd4a2b94cf63d06c155e): Indexes: one CustomIndex two three PandasIndex 2. mark unique indexes with a prefix to make it look like a list (see 9b90f8bceda6f012c863927865cc638e0ff3fb88): Indexes: - one CustomIndex two - three PandasIndex 3. use unicode box components (in front of the coordinate names) (see 2cec070ebf4f1958d4ffef98d7649eda21ac09a3): Indexes: ┌ one CustomIndex │ two └ three four PandasIndex 4. use unicode box components (after the coordinate names) (see 492ab47ccce8c43d264d5c759841060d33cafe4d): Indexes: one ┐ CustomIndex two │ three ┘ four PandasIndex

For the unicode box components, we can choose between the light and heavy variants.

@benbovy and I think the unicode variants (especially variant 3) are the easiest to understand, but we would need to decide whether we care about terminals that don't support unicode.

Edit: in the meeting we decided that support for the subsection of unicode should be common enough that we can use it. I'll clean this PR up to implement option 3, then.
