Description Dave Jones 2006-06-14 23:19:41 UTC

This mbox http://people.redhat.com/davej/muttbork.mbox contains two mails, where
the patches appear to be mangled when viewed in mutt.
In the first mail
([Ubuntu PATCH] Make btsco headset (a bluetooth device) work)
The diff appears line-wrapped like so ...

-               hdev->sco_pkts = hdev->sco_cnt =
__le16_to_cpu(bs->sco_max_pkt);
+               hdev->sco_pkts = hdev->sco_cnt = bs->sco_max_pkt ?
__le16_to_cpu(bs->sco_max_pkt) : 8;

instead of showing as two wide lines.

In the second mail, the leading whitespace at the beginning of unpatched lines
of the diff has been eaten.

The mails have format=flowed parameter in content-type. Therefore mutt tries to
interpret the format, see RFC 3676 for details. It is better to avoid posting
patches in flowed format. Blame the sender :)

Comment 2 Dave Jones 2006-06-17 18:19:15 UTC

Is this a recent change in mutt behaviour ? 
I'm noticing that quite a few mailers (including thunderbird) send stuff that
way, and I've not noticed this mangling until the last week or so.

Comment 3 Miroslav Lichvar 2006-06-18 09:18:06 UTC

No, there wasn't an update for very long time. I tried CVS version of mutt and
result is exactly the same.

Searching "format=flowed" on mozilla's bugzilla shows a lot of bugs. Maybe this
is one of them.
