key bindings reported incorrectly

[Ilya N. Golubev]

Versions: 20.7, 21.4a

Environment: viper enabled.

In help buffer formed by `f1 b', when viper vi movement mode is in
effect, `f1 k N' reports:

N runs the command viper-search-Next
   which is an interactive compiled Lisp function in `viper-cmd'.
(viper-search-Next ARG)

So does `f1 b' report.

Actually `N' does nothing in that buffer.  `/' was already invoked.
In this case `viper-search-Next', if ever invoked, always either
changes point or outputs <Pattern not found> message.  So it appears
that the command reported to be bound to that key is not invoked at
all.
