text_set assumes a complete replacement of the entire document with
something different, in which case moving to cursor position 1 is
appropriate.
If you are replacing with something identical or close to the current
content, you should instead create a Padre::Delta object with
Padre::Delta->from_scalars and then apply the delta to the current
document. Delta objects are applied in a way that retains the correct
location of the cursor and scroll in the kinds of scenarios where a
document is being modified rather than replaced wholesale.
Padre::Delta is new in 0.92, so it would mean WebGUI needs to upgrade
to support 0.92.
