        <pre>So the idea is to have possibility to help clang-format with guessing language
of a file by narrowing possible options list.

For example, if a project (a directory) contains .clang-format and -style=file
was selected, then limit options only to the languages described in that file.
This could help in cases like 37433, 39216: if there is no configuration for
ObjC, then do not consider ObjC.

Other option would be to have an option in the configuration file and CLI to
explicitly define a set of languages to choose from. This is pretty similar to
what was proposed in 36468.</pre>
