[Lldb-commits] [lldb] [lldb] Add a setting to customize the prompt color (PR #66218)

[Jim Ingham via lldb-commits]

We actually have several requests for this internally, and I think that's a good idea.  

However, some of the format tokens can return arbitrary text, including newlines, for instance "thread.completed-expression", and all the "script." ones.  Do we want to try to support prompts with new-lines or do we want to restrict the format string for prompts or somehow cut off these arbitrary elements at the first new-line?
