Please write something like "(space bar)". The string "SPC" appears to
be an acronym, i.e. three words beginning with the letters S, P, and C
respectively. This is very confusing.

(And I know `top(1)`'s online help (key `h` or `?`) shows "SPC", too.)

Commit c8aa5e526fc02c360b09718a7dcb5db1876dca05 removes the mapping
of `\f` (form feed) to `CMD_redraw` (see `command_chars`). Commit
b26cf3d06cf3eb014c93aef569748e60feae1911 does not associate any char
with `CMD_redraw` (in `all_commands`).

Eventually commit c8aa5e526fc02c360b09718a7dcb5db1876dca05 introduces
the line `{' ', "update the display", false, CMD_update},` but this
is actually the update command.

If I do something like `printf '\f' > /dev/ttyv1` (where `ttyv1` runs
an instance of `top(1)`) I do not observe any change (except the
cursor moving one box down till the next refresh).
