Command-history was added on "later" (mostly my changes).

The way command-history works messy :-(

It's also messy to modify :-(

Basically, each of the prompts that you can get during a command is a
separate piece (address and the first command-verb are a special case). 
vile glues the pieces together to keep in [History], and when doing an
up/down arrow to scroll through history is using the current position in
the built-up line to decide which piece it can use for completions.

Addresses don't fit well into that scheme.  I recall thinking it could
be improved by making vile smart enough to not care how long the address
is.  But then there's the problem of deciding whether to scroll through
the different address expressions or just the commands that follow the
addresses.

The difference between forward/backward searches is another nuisance
(which I've thought about special-casing to make it less annoying).
