bug#64776: 29.0.91; doc string of `ignore'

[Drew Adams]

1. The two "and"s here are confusing.  Maybe say something like this:

     It is bound to key sequences M-<noname>, C-<noname> and
     C-M-<drag-mouse-1>, and to many ordinary text characters.

2. TheA &rest argument, such as ARGUMENTS here, is singular; its value
   is a list of actual arguments.

   This is incorrect; there is only one &rest argument, and its name
   here is ARGUMENTS.

   This:

     This function accepts any number of ARGUMENTS, but ignores them.

  should be this:

     This function accepts any number of arguments, but ignores them.
