The presentation of diagnostics to the users is different between clang and clangd:

- clang diagnostics are always prefixed with the file, location and severity of the diagnostic, e.g. `main.cpp:1:2: error: expected '}'`
- In LSP clients (VSCode in particular), the diagnostic message is the first thing the user sees and it looks a little nicer (subjectively) if the first letter is capitalized.

See the screenshots from VSCode on how diagnostics are presented:
