* Fixes#2437: Shift remaining ranges when applying multi-edit formatting
A formatting request to a language server may result in a list of
multiple text edits. The ranges of all these text edits are based on the
yet unmodified document. Che applies the edits to the document one by
one. If the inserted text has a different length than the replaced text
then the ranges of the remaining edits become invalid and they must be
shifted appropriately.
This patch shifts the ranges as necessary. To achieve this, it first
converts the ranges based on lines and characters to linear ranges,
which are easier for shifting.

* Reworked: just applying the text edits backwards is enough
