Which version of Emacs and ada-mode are you using? I see "goto"
highlighted with font-lock-keyword-face, as expected.

Can you send a fragment of Ada code showing the problem?

GNU Emacs 22.3.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2008-11-15 on localhost

(Gentoo package app-editors/emacs-22.3)

Execute "emacs prov.adb" (in a directory without such a file). Then
write these lines:
procedure Prov
is
begin
    goto done

The reserved words "procedure" "is" and "begin" get highlighted as soon
as they are written. But "goto" is only highlighted if
1. the file is saved at this point,
2. a ';' is written, or
3. a newline is written

Compare this with the similar example
procedure Prov
is
begin
    raise done

Here the reserved word "raise" is highlighted immediately (unlike
"goto"). (But the identifier "done" is not highlighted immediately,
which looks like another bug.)

I'm testing on 23.0.60 (current trunk from the CVS repository), but
AFAICS, there's no significant difference between the two ada-mode.el
packages that should affect font-locking.

That's not exactly the behavior I see, but I certainly see that goto
is not highlighted after the final "o" is written. The same happens
for "use", for example. That is expected, see the variable
ada-font-lock-keywords.

I'm not sure they are bugs. No one said font-locking should be
instantaneous; often some context is needed.

Let's wait for Stephen's opinion.

I agree with Juanma's analysis; this is not a bug, it's a feature of
font-lock.
