Red Hat Bugzilla – Bug 195396
mutt is mangling mail in its viewer
Last modified: 2015-01-04 17:27:26 EST
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 :)
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.
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.
