Improve psql's behavior when the editor is exited without saving.
When editing the previous query buffer, if the editor is exited
without modifying the temp file then clear the query buffer,
rather than re-loading (and probably re-executing) the previous
query buffer. This reduces the probability of accidentally
re-executing something you didn't intend to.
Similarly, in "\e file", if the file isn't actually modified
then don't load it into the query buffer. And in "\ef" and
"\ev", if no changes are made then clear the query buffer
instead of loading the function or view definition into it.
Cases where we fail to invoke the editor at all, or it returns
a nonzero status, are treated like the no-file-modification case.
