Now if query_buf is empty previous buffer contents is used.

​IIUC the complaint is that it is no longer possible to use \edit​ to generate a completely empty temporary query that can then be written from scratch.

The v10 behavior is desirable so that leaves either learning a new idiom to accomplish your goal or adding something like "\edit -" to explicitly invoke the desired behavior.

Doing:

# SELECT <enter>
# \edit

Seems reasonably straight forward to get a editor for a newly query instead of the previous one.
