I'm asking for permission to apply the following CEDET non-regression
bug fixes to the emacs-24 branch. They fix some pretty annoying bugs but
are so small that I think they should be safe to commit.
- Patch1: Fixes a bug where C++ system headers like "vector"
are not recognized as C++ and hence parsing fails. The bug was that
`enable-local-variables' was erronously set to 'nil' when loading
those files, but it should be ':safe', so that the magic comments are
recognized.
- Patch2: Without this fix, the interactive function
`semantic-symref-symbol' simply does not work at all, so it cannot
possibly make anything worse.
- Patch3: Move to beginning of completions when pressing TAB at the end
of the Completions buffer.
- Patch4: Fixes a very annoying, long-standing bug were active buffers
were killed when using GNU global and file was loaded through a
symlink.

From what you say, it's OK.

This will signal an error when *Completions* is not displayed anywhere.

We need to do something to avoid those problems. AFAIK there's no
reason to ever prefer get-file-buffer over find-buffer-visiting, so
maybe we should simply get rid of get-file-buffer and make it an alias
of find-buffer-visiting.

At this stage, there must be a *Completions* buffer, otherwise it's an
error anyway. But regarding the freeze, I will wrap something around
that making sure it exists.

Oh, you have my vote for that. But I have a hunch you won't put this
change into the emacs-24 branch, so I read this comment as "Fine, please
commit". ;-)

Actually, it's worse: it will signal an error when *Completions* is not
displayed in the selected frame. IOW in my config it will always signal
an error.

I'd rather keep this for trunk:
- it's not safe.
- It's not a regression.
- It's not even a bug fix: it improves behavior more than it fixes a bug.

Great! How much (time and effort) are you willing to contribute to
my campaign?

Huh? How did you guess?

Indeed,

OK.

Can't I just give you money?
Anyway, do you plan on actually replacing all `get-file-buffer's? That
would have to wait for the release anyway, I guess.

If you want to give me money additionally to time and effort, that's
fine, yes.

"Plan" is a big word here. But if someone could take care of making
get-file-buffer an alias of find-buffer-visiting (and checking that it
doesn't introduce any obvious problem), that would be appreciated.
