[cfe-dev] overwrite rewritten text

[Jonas Toth via cfe-dev]

I am a bit puzzled of what you want to achieve.

AFAIK the change must be applied to the file and then the AST must be
recreated to get the new Source Locations, but if you `InsertText`
something and then `RemoveText` at the same location and same length
what do you intent to do?
For me this sounds like just replace a piece of original code with new
code. Otherwise that would be a no-op, not?
