271733 - Use pref mailnews.localizedRe for subject threading

Status: RESOLVED INVALID

(Thunderbird :: Mail Window Front End, enhancement)

Description

[Andreas Lange]

Since bug 213004 we have a pref for setting localized Re-strings so that reply
can strip silly chains like "Re: SV: Re: SV:" that tend to appear when mixing
sane clients with some Microsoft software.

It would be nice to also use this pref when threading subjects in the folder
view so that even those messages with the silly subjects end up together. :-)

The pref is currently only used here:

Hmm. This might be totally invalid, after some closer inspection I think the
thread pane already shows the Re-stripped subject. I'll keep the bug open as a
reminder to look into why the localizedRe pref doesn't work though.

Silly me. This works perfectly well. But, one must zap the .msf file first if it
was created without the pref set since the stored header flags for MSG_HAS_RE
will be wrong. It is only used for new messages otherwise.
