MIME encoded subjects in Summary

[Uday Reddy]

When a message has a MIME encoded summary line, its embellishment in the Summary buffer often has no spaces. The Presentation buffer shows it fine.

(A test message in test-mime from Fengjie Zhou.)

It is very likely that this is happening because the cached-data saved to disk in the message headers is handled incorrectly. Perhaps the new cached-data fields such as vm-summary-subject are not being encoded and decoded correctly?

In fact, doing `V s' which searches for subject line strings is not working
for these messages. So, the cached-data is trashed.

[Uday Reddy (reddyuday)]

The X-VM-v5-data headers are not being decoded at all at present. Surprising that they ever worked.

The MIME encoding of these headers was introduced in rev. 453.6.16. But I don't see any decoding of them. Perhaps the decoding of the summary lines was done in an ad hoc way. Other data was never decoded.

Follow-up revisions in 453.6.23, 453.6.28, 610, 611, 789.1.x ("subject" branch) merged in 792, etc.
