Describe the feature

Show a list of directories with a single child directory as a single entry.

This is something that other editors (particularly used for Java development) do, but can also be found in GitHub, for example:

You can see above how resession/extensions are collapsed into a single entry as resession has no other child apart from sessions.

This could also go further and collapse multiple levels of directories into a single entry.

Provide background

Working on environments where the directory structure translates to the package structure of the language, this is a very common use case. As mentioned before, an example of this scenario is developing Java code. In these cases, a flat representation of this structure whenever this happens proves to be very helpful and improves the experience when exploring the code.

What is the significance of this feature?

Duplicate of #311. This feature is still not a good fit for oil for the reasons listed in that issue.
