Hello Gnus,
This is my first post to this list, so please forgive me if i break all
the written and unwritten rules. [and my first posting hasn't showed up
after 16h, so this is potentially a double-post]
I recently ran into an issue where a French speaker i was communicating
with had "Re : ..." as their reply subject prefix (note the leading
space before the colon). This quickly ended up with us bouncing emails
around with such lovely subject lines as "Re: Re : Re: Re : Re: ...", et
cetera, ad infinitum. This phenomenon, of surrounding certain
punctuation marks with extra spaces, turns out to be A Thing™ in French
writing [0]. I discovered that by making a very small modification to
the term `message-subject-re-regexp`, the problem was solved for me,
locally (it's in my configuration files ATM). But since this might be
something that's useful to others, i threw a patch together, attached.
Of course, i could understand if such cultural (non-anglophone?) cruft
were undesirable in the Gnus code base, but perhaps others might benefit
from this. If not, i am sorry for wasting your collective time. If the
fix is desirable yet wrong in some other way, rest assured that you all
have my deepest apologies, i don't mean to step on anyone's toes.
Thank you and have a good day,
p.

It's useful and I don't see any problem with that patch. Perhaps you
should repost it with a subject like "[PATCH] ..." or do M-x gnus-bug.

On a side note I have solved this outside of Gnus in procmail with this in my
.procmailrc:
#
# Fix Subject RE/SV/AW line for MSExchange/MSMail/MSOutlook
# Also fix Subject field for Norwegian android mailer ("Vedr").
# No X-Mailer field to rely on, unfortunately!
# Remove MSE quotes of type "'Real Name'"
#
:0 fhw
| /usr/bin/perl -ne "s/\?[Ww]indows-1252\?/?iso-8859-1?/g; s/^(Subject:)\s+(S[Vv]:\s*|AW:\s*|Ad:\s*|Vedr:\s*|R[eE](\(\d+\))?:\s*)+/\1 Re: /g;s/^(Subject:)\s+(=\?((iso|ISO)-8859-1|us-ascii)\?Q\?)((S[Vv]|AW|Ad|R[eE](\(\d+\))?)(:|=3[Aa])_*)+/\1 \2Re:_/g; s/\042\'([^\']*)\'\042/\042\1\042/g ; print"
As this regular expression shows there seems to be a great deal of
creativity when it comes to messing up subject headers. Everything
matched here has been encountered in the wild.

But this is already a customization option, shouldn't we just let users
customize it? Is this one tweak worth it?
