22.2.50; doc strings: menu-bar-mode scroll-bar-mode tool-bar-mode

[Reiner Steib]

Hi,

maybe the doc strings of menu-bar-mode, scroll-bar-mode and
tool-bar-mode should be unified with regards to the numeric arguments.
Currently, some of the doc strings mention positive, some negative
arguments:

| (menu-bar-mode &optional arg)
| [...] 
| With a numeric argument, if the argument is positive,
| turn on menu bars; otherwise, turn off menu bars.

| (scroll-bar-mode &optional flag)
| [...]
| With a numeric argument, if the argument is negative,
| turn off scroll bars; otherwise, turn on scroll bars.

| (tool-bar-mode &optional arg)
| [...]
| With numeric arg, display the tool bar if and only if arg is positive.

Bye, Reiner.
