Ah crap.  I'd replied via gmail ; today and occasionally in the past as
a convenient short cut when not reading netdev with a "normal" MUA.  And
this is not the 1st time gmail has randomly decided to be "helpful" by
mangling plain text like this.  Well, I'll be having no more of that BS.

Sorry about that; I know you don't need the extra stupidity to deal
with, esp. at this point in time.  Original plain text follows, courtesy
of reliable 1990's MUA technology -- the pull details remain unchanged.

Paul.

I'd hate to see a garbage collection miss out from integration due to
wider testing, so I've taken Joe's commit, put it on today's net-next
and made the following changes:

  -keep magic number references but mark them obsolete (nobody asked for
   this, but it made sense to me).

  -keep the wanrouter.h (uapi and kernel-centric one) files, but with
   only the X.25 bits that caused build failures.  I have trimmed the enum
   to just the bits that were used.  Obvious build failures like davem
   reported aside, I was concerned that userspace might reference the
   headers (got caught on this for my token-ring deletion).  I did not find
   any userspace uses, but it was packaged with most distro's libc header
   content, so who knows?  As I did run into this with the token ring
   delete, so this is the safer route here -- i.e. leaving a skeleton
   header.

I don't want to spam everyone with another giant patch, so note that a

I was curious to better figure out what triggered this, now that it
isn't 1AM.  It seems the original wasn't plain text, and that gmail
didn't know what else to do with the content from your message when it
arrived as base64 encoded.  It looks like it arrived that way to the
list archivers too, and they failed to do anything sensible with their
copy of your message as well.

I only wonder which component is at fault here, the producer side (it
gives the following headers),

 Content-Type: Text/Plain; charset=iso-8859-7
 Content-Transfer-Encoding: base64
 (and the _absence_ of any MIME chunkwrapping)

or the receiver side. (Al)Pine and derivates displays the message
fine, marc.info does not, and gmail presents the body after literally
taking a stab at it.

Patch

diff from Joe's original and my amendment is shown below (warning - cut
and paste damaged ; not that anyone sane should, but don't try and apply
this delta; it is for review purposes only -- and all lines with "+" are
just restoration of what lines were already there).

For the folks well adapted to git already, I've pushed an equivalent
branch that I have done the build testing of an x86_64 allyesconfig and
allmodconfig, and they compile OK.  This is based on the net-next of
today:

The following changes since commit bf0098f22ca7b59e8844ac6882bbae230d34b98d:
