MaskRay's random complaints about Language Server Protocol

Completion

• VSCode sorts sortText case insensitively.
• VSCode only allows length-one strings in CompletionRegistrationOptions.triggerCharacters https://github.com/Microsoft/language-server-protocol/issues/138 (closed) Server developers have to work around that. CompletionTriggerKind::TriggerCharacter should extend as well.
• The order of textEdit additionTextEdits is not specified.

Formatting

• firstTriggerCharacter and moreTriggerCharacter should be unified

Miscellaneous

• interface Position uses UTF-16 counting for character. https://github.com/Microsoft/language-server-protocol/issues/376
• interface Command (workspace/executeCommand) is VSCode centric.
• textDocument/implementation isn't clear. textDocument/definition isn't clear when it comes to the difference of declaration/definition.
• namespace DocumentHighlightKind is not a bitmask. Read and Write cannot coexist.
• Why can't we get more namespace SymbolKind constants sooner? https://github.com/Microsoft/language-server-protocol/issues/344
• textDocument/signatureHelp: the position of ParameterInformation::label is unspecified: it is difficult to highlight ParameterInformation::label in SignatureInformation::label
