- The changes are "atomic" - if any changes can't be applied,
- none of them can be (tracked by the m_valid flag).
- Similarly, attempts to add the changes from a rich_location flagged
- as containing invalid changes mean that the whole of the edit_context
- is flagged as invalid.
-
- A complication here is that fix-its are expressed relative to coordinates
- in the files when they were parsed, before any changes have been made, and
- so if there's more that one fix-it to be applied, we have to adjust
- later fix-its to allow for the changes made by earlier ones. This
- is done by the various "get_effective_column" methods. */
