Patch 7.3.429

[Bram Moolenaar]

Patch 7.3.429
Problem: When 'cpoptions' includes "E" "c0" in the first column is an
error. The redo register is then set to the errornous command.
Solution: Do not set the redo register if the command fails because of an
empty region. (Hideki Eiraku)

The History of every major Galactic Civilization tends to pass through
three distinct and recognizable phases, those of Survival, Inquiry and
Sophistication, otherwise known as the How, Why and Where phases.
For instance, the first phase is characterized by the question 'How can
we eat?' the second by the question 'Why do we eat?' and the third by
the question 'Where shall we have lunch?'
-- Douglas Adams, "The Hitchhiker's Guide to the Galaxy"
