IDE (IntelliJ IDEA) support for Raw String Literals

I have a couple other requests for IntelliJ's behavior with raw string
literals. It would be helpful for me if I could get some sense of how
likely these features would be to be implemented.
The requests apply to either of these cases:
- Case 1: If we decide to implement automatic stripIndent behavior for
- Case 2: If we decide not to, but for the particular string literal in
question, IntelliJ recognizes that stripIndent is being called.
In either of these cases,
- Will IntelliJ automatically maintain the leading indentation inside
the RSL in the same way it handles leading indentation outside it?
- Of course, there is an issue in "Case 2" that when you are first
typing you won't have *typed* stripIndent yet, so it won't know
whether you are planning to. There could be a user preference that
automatically inserts `.stripindent() at the end when you type the
opening delimiter; that would help.
- Could IntelliJ compute the region of the source file that will be
included in the resulting runtime constant, and render that boundary
visually on the screen (either as a border, or a different shading for the
- When the user is highlighting text, as long as the endpoints are both
within the delimiters, can the highlighted region be automatically
restricted to that boundary? That is, exclude whitespace that is recognized
as indentation that will be stripped. This would make pasting raw text to a
different file much cleaner/easier.
