[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. 0. <http://www.btb.termiumplus.gc.ca/tcdnstyl-chap?lang=eng&lettr=chapsect17&info0=17.07> [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #2: 0001-message.el-message-subject-re-regexp-More-liberal-re.patch --] [-- Type: text/x-diff, Size: 1314 bytes --] From 62c0f7262acae856dcd43cb4fb7868c5dc1ec857 Mon Sep 17 00:00:00 2001 From: Paul van der Walt <paul@denknerd.org> Date: Fri, 14 Aug 2015 22:27:07 +0200 Subject: [PATCH] message.el (message-subject-re-regexp): More liberal regex. * message.el (message-subject-re-regexp): Match French style ("Re :") reply subject prefixes. --- lisp/ChangeLog | 5 +++++ lisp/message.el | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/lisp/ChangeLog b/lisp/ChangeLog index 324f473..05d68f0 100644 --- a/lisp/ChangeLog +++ b/lisp/ChangeLog @@ -1,3 +1,8 @@ +2015-08-14 Paul van der Walt <paul@denknerd.org> + + * message.el (message-subject-re-regexp): Match French style ("Re :") + reply subject prefixes. + 2015-08-06 Paul Eggert <eggert@cs.ucla.edu> * message.el (message-send-form-letter): Change (message (format ...)) diff --git a/lisp/message.el b/lisp/message.el index 26655f3..54be212 100644 --- a/lisp/message.el +++ b/lisp/message.el @@ -300,7 +300,7 @@ any confusion." regexp)) (defcustom message-subject-re-regexp - "^[ \t]*\\([Rr][Ee]\\(\\[[0-9]*\\]\\)*:[ \t]*\\)*[ \t]*" + "^[ \t]*\\([Rr][Ee]\\(\\[[0-9]*\\]\\)* ?:[ \t]*\\)*[ \t]*" "*Regexp matching \"Re: \" in the subject line." :group 'message-various :link '(custom-manual "(message)Message Headers") -- 2.5.0 ^ permalink raw reply [flat|nested] 6+ messages in thread

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. ^ permalink raw reply [flat|nested] 6+ messages in thread
