Support for pull request by language

[surli]

Is your feature request related to a problem? If so, please describe.

We are starting to set up in XWiki a new process when a new language is introduced in the platform because we need to perform some checks to ensure the language will be properly supported by our search engine etc.
The problem is that all contributions made in Weblate are currently sent in a unique pull request on our repository, so a pull request mixes changes related to multiple language. If we need to perform checks for adding a new language (that we see because of a pull request submission), it means that we'll block all other changes until we performed the checks (and possibly some changes in our code).

Describe the solution you'd like

It would be nice to be able to receive different pull requests depending on the language translated. It would prevent us blocking contributions in other languages when a new language is added. It would probably also help reviewing the contributions: we mainly do the review process by checking the PR.

Describe alternatives you've considered

Right now we don't see many alternatives: we are gonna block the PR until we're ready to merge them.

This would be quite complicated to implement - Weblate has one working copy of the repository and having multiple branches to allow pull requests per language would add a lot of complexity. You can always cherry-pick commits from the pull request if you don't want to merge it fully.

Well I can imagine that it would be lots of work to add in Weblate, but I think it might be an interesting way to go. Supporting multi-branches could also allow some other features such as having different PR per components in case of linked components.

Sure, but that's manual work, the idea here is to have an process more automated.

You don't have to use linked components, and you will get separate PRs then.

This issue has been put aside. It is currently unclear if it will ever be implemented as it seems to cover too narrow of a use case or doesn't seem to fit into Weblate. Please try to clarify the use case or consider proposing something more generic to make it useful to more users.

What might be a more generic solution to this is #7271 - each underlying repository would get a pull request, even if the repositories would be actually the same.
