pipenv's Trivia patch to make tomlkit dump toml's inline table

Comienza comparando tomlkit/container.py y tomlkit/items.py con el parche de vendor de pipenv referenciado, centrándote en el manejo de Trivia, Comment e InlineTableDict. Revisa la cobertura de pruebas existente para el volcado de tablas inline y, después, verifica el comportamiento final con respecto al parche sin cambiar código vendorizado no relacionado.

pipenv applies a patch to their vendored copy of tomlkit, and it seems that it doesnt exist here yet.

The patch is https://github.com/pypa/pipenv/blob/master/tasks/vendoring/patches/vendor/tomlkit-fix.patch

Parts of that have been merged, but the bit that looks missing is:

Is this an appropriate addition to tomlkit?

It appears the author was @frostming , originally at https://github.com/pypa/pipenv/commits/6df7d8861da841e552049dcde9ff9a0f23edc01e/tasks/vendoring/patches/vendor/tomlkit-dump-inline-table.patch

I dont see any similar patch in https://github.com/sdispater/tomlkit/commits?author=frostming

Ideally they should be submit the patch, or someone elses should submit it with the patch author set to the correct author. Ping also @techalchemy who has been heavily involved in the pipenv vendoring.
