It looks like the 'font-lock-face text property is not preserved under
killing and yanking.
Here is a recipe to reproduce the problem:
- Go to *sratch* and type some text.
- Select it as region and do
(put-text-property (mark) (point) 'font-lock-face "bold")
- Kill and yank the region and notice that the bold face is gone.
Also, I wonder if there is a good reason why 'mouse-face is in
yank-excluded-properties. If there isn't one, then perhaps you can
remove it too.
Cheers,
Uday

Well yes, people used to complain that copying text would copy unwanted
font-locking along with it. Eg
http://lists.gnu.org/archive/html/emacs-devel/2006-09/msg00981.html
Why do you think it should be preserved?

My context was in writing email messages in mail-mode/message-mode,
both of which use font-lock to fontify the headers and the cited text.
VM has functions that put "attachment buttons" into the mail-mode
buffers, which are have data stored in text properties. I wanted to
put a face on them to make them look like "buttons". It works fine
normally but it is not preserved under killing and yanking.
I find the above thread a bit confused, or perhaps I am hopelessly
confused. It appears that the 'font-lock-face property has been
installed so that font-lock-mode doesn't mess with it. I don't see
any "unwanted font-locking" in the 'font-lock-face property. So, why
should it be erased by yanking? It should work the same way as the
'face property works in a non-font-lock-mode buffer.
Certainly, when you want to move text around within a single buffer,
you don't want to lose faces by killing and yanking. If it gives
undesirable results when people want to move text from one buffer to
another, then they might need to use a separate function to erase the
fontification or they might use the yank-excluded-properties variable
to exclude font-lock-face.
Perhaps, I should reopen the discussion in the emacs-dev list?
Cheers,
Uday

The reason font-lock-face is removed in buffers in which font-lock is
active is that font-lock-face is typically applied by programs, so it
would be wrong for a user-level operation like yanking to apply it.
This is a rule of thumb; there is no right or wrong answer. If you
prefer to preserve font-lock-face, I've added to trunk a new option
`yank-handled-properties' which can be customized to get the behavior
you want.
