Review request for KDE PIM.


Summary
-------

Parse correctly malformed multi-line mail headers. When the next header line starts with =09/=20, it is apparently an encoded tab/space character that marks header continuation.

The solution is different to former kmime patch, because old kmail used mimelib and parsed messages itself too.

Fixes bug 86302 for kmail-4.4. This should not add any regression AFAICT.


This addresses bug 86302.

Testing
-------

Running kmail, opened wrongly coded mails. Example of wrongly coded header looks like this:

...
Cc: =?us-ascii?Q?linuxwacom=2Ddevel?= <linuxwacom-devel at lists.sourceforge.net>
Subject: =?us-ascii?Q?Re=3A=20=5BLinuxwacom=2Ddevel=5D=20=5Bxsetwacom=5D=20xsetwacom=20=2D=2Dset=20=22WACOM=20Pen
=09Tablet=22=20STopX0=20500=20fails?=
...

Note the =09 at the beginning of the second Subject line.


Thanks,

Oldrich
