%name-prefix: manual not consistent with bison

[Rui Maciel]

I've just noticed that the manual entry on the %name-prefix option isn't
consistent with the way Bison handles this option, as, while the manual
states[1] that the option should be used like:

%name-prefix "prefix"

When Bison stumbles on that entry it throws an error. On the other hand, it
accepts the following:

%name-prefix = "prefix"


Another aspect which would be nice to have on that part of the manual is a
reference to the implications that option has on the demands it imposes on the
lexer.

In Bison 2.3b, we added support for the first form above and deprecated
the second form.  Please check that the bison executable you're running
and the version of the documentation you're reading have the same version
number.

The documentation on %name-prefix gives the list of external functions and
variables that it renames, and the list includes those that the lexer must
interact with.  Is there something else you think should be mentioned?

It's Bison 2.3, installed from the Ubuntu repositories.  The manual page
appears to be for Bison 2.4.1.

it appears then that 2.3 is an older version than 2.3b.So, to put it in other
words, it appears I need to upgrade bison. Darn it.

Weird. That's exactly what I wished for. I don't know if I should be glad that
my wishes have been met or if I should kick myself for not opening my eyes
while RTFM.

Nonetheless, thanks for the help. Kudos!
