I’m not sure of what wasn’t clear so I’m how to reexplain but:

The point was, say, in the middle of the SRC block, and (as I said in
the subject) after the operation, was moved: at the end of the block.

This must be because I deleted a region of text (the whole SRC block)
then reinserted it (or rather, its original content, so that to restore
buffer as before), so the point is after the insertion.

However, I’d have expected save-excursion to put the point again where
it was inside the block.  So either it does save it as a buffer position
but garbled it when deleting region, either it does with a marker and
this very one wasn’t saved within the portion of text I later
reinserted…

Is there something such as `restore-markers'/`save-markers' that would
allow me to restore point after doing this operation?  Or better some
`save-buffer-content' like `save-excursion' but restoring the buffer
afterwards?
