!   Change Log:
!
!   2004-01-11 Volker Kuhlmann <VolkerKuhlmann at gmx.de>
!   - improved from Thorsten Haude's basic version:
!   - quoted lines which are empty coloured correctly
!   - 2. and 4. colour swapped, the new 2. colour is easier to read
!   - regex for attribution line extended, though nothing will ever fit
!     all possibilities there
!
!   2004-01-12 Volker Kuhlmann <VolkerKuhlmann at gmx.de>
!   - extended to colour the headers if present, and the important headers
!     in a different colour
!   - handles pseudo-mbox format mailboxes
!     Note: This takes about 1.2s/MB on a P3-450 on first load of the file
!   - changed some constructs to non-capturing (faster)
!   - need context-rescan-lines of 2 for editing headers
!   - extended language mode
!
!   2004-01-12 Thorsten Haude <nedit at thorstenhau.de>
!   - changed some formalities on Volker's work
!   - changed some colors
!   - changed some pattern names
!   - use only required headers (From and Date) to recognize a header block
!   - brushed up language mode
!   - removed some false case insensitivities
!   - make signature pattern more strict
!
!   2004-01-15 Volker Kuhlmann <VolkerKuhlmann at gmx.de>
!   - Tried to come up with a new expression which also highlights headers in
!     mails not in mbox format (doesn't have a From_), but the expression isn't
!     very nice. In this case there will be only one mail per file. When
!     composing with mutt, there is no Date: line (as that gets added during
!     sending).
!   - Made header field names case-insensitive again. Is there an application
!     which requires them to be case-sensitive? This remains to be decided on.
!   - Header fields are delimited by colon and possible *white* space (not
!     space). Dunno whether this white space is even optional.
!   - experimentally changed colour of attribution line
!   - created a third test file
!
!   2004-07-20 Thorsten Haude <nedit at thorstenhau.de>
!   - Bumped up version number to 3.0. This is unchanged from what was
!     called 1.2, but I saw a version 2.0 which was clearly less evolved.
!
!   2004-08-14 Thorsten Haude <nedit at thorstenhau.de>
!   - Bumped up version number to 3.0.1 because I forgot to change the
!     README pattern (doh).
!   - Header *are* case-insensitive according to the RFC 2822.
!
!   2013-09-06 Volker Kuhlmann <VolkerKuhlmann at gmx.de>
!   - Allow certain headers to appear in any order when detecting the start of
!     the headers. Require 3 of them.
!   - Make language detection pattern more flexible, add extension ".eml".
!   - Show quotes at level higher than 6 in the same colour as level 6.
