Date: Wed, 28 Jan 2009 16:34:39 +0100 (CET)

I have a po file opened in the background, and every time I want to exit Emacs, Emacs reminds me of saving this po file although I haven't changed anything.  Apparently, Emacs has silently duplicated its header so that it starts with

This is a bug in po-mode.el which is part of gettext, not Emacs.  It is
already fixed in gettext CVS since yours truly had reported it some time
ago, see
http://lists.gnu.org/archive/html/bug-gnu-utils/2008-08/msg00006.html.

Cheers,
       Sven

This is true for the header duplication, however, the *silent*
modification of the po file in the background (i.e., without
explicitly reverting or opening the file) happens in CVS Emacs since
two weeks ago or so.

Tschö,
Torsten.

What do you mean with that?  IIRC, just visiting a po file (more
exactly, switching to po-mode) runs po-check-file-header and modifies
the buffer by inserting the double header.  This has been true for a
long time.

I visit the file, and close Emacs.  Then I re-start Emacs (I save my
desktop to a file, so every buffer is restored), and the po header
is not duplicated.  I keep it visited but work on completely
different files all day long.  Then I quit Emacs and it complains
that there are unsaved modifications in the po file (namely, the
header duplication).  The po file hasn't been touched by a
third-party program meanwhile.

I can't really preclude that something in my setup has changed, but
it looks to me as if Emacs has changed recently.

Tschö,
Torsten.

In this situation Emacs should ask about saving the buffer, since it is
modified.  And it does that for me.

Huh?

Emacs does this for me whenever I close it.  But I don't use a desktop.

Well, I played around a bit twice today, and honestly I don't
understand the rules when po-mode wants to update the buffer.
Changing "PO-Revision-Date" seems to trigger it but not always.  You
probably know the rules much better than me.

I *suspect* that everytime my desktop was restored, the PO buffer
was immediately updated and thus changed.  When I quit Emacs, I got
the message about an unsaved buffer.

Anyway, if a solution of the "header duplication" issue highly
probably also solves any other superfluous update of the PO buffer
-- which would render the buffer changed -- then please close the
ticket.

Thank you!

Tschö,
Torsten.

Not really, I'm not a po expert either.

Yes, that is certainly the case.  Loading the desktop restores major
modes, thus runs po-mode => po-check-file-header inserts another
header.

I have already reassigned it to `notemacs' since it's in po-mode.el (and
already fixed in gettext CVS).

Cheers,
       Sven
