For a long time `nix repl` has supported displaying documentation set on
builtins, however, it has long been convention to use Markdown comments
on Nix functions themselves for documentation. This exposes that
information to `nix repl` users in a nice and formatted way.
NixOS/rfcs#145 doc-comments are primarily what this feature is intended
to consume, however, support for lambda documentation in the repl is
experimental. We do our best effort to support the RFC here.
These changes are based on [the nix-doc library](https://github.com/lf-/nix-doc) and
are licensed under the terms described in the relevant source files.

| Experimental REPL support for documentation comments using `:doc` | 564 |
Using :doc in the REPL now supports showing documentation comments when defined on a function.
Previously this was only able to document builtins, however it now will show comments defined on a lambda as well.
This support is experimental and relies on an embedded version of nix-doc.
The logic also supports limited Markdown formatting of doccomments and should easily support any RFC 145 compatible documentation comments in addition to simple commented documentation.
