bug#3504: 23.0.94; Non-standard key notation in Ada manual

[Drew Adams]

Just happened to notice that at least some of the Ada manual uses a
non-standard key-sequence notation.  See node `No project files'
(which should probably be `No Project Files':
 
 <C-x `> (on a PC keyboard, <`> is next to <1>)
 
That should probably be `C-x `', not <C-x `>.
 
Not sure how the keyboard keys ` and 1 should be notated - perhaps
like this? (on a PC keyboard, ``' is next to `1')
