I noticed recently that vim does not always set 'filetype' to "mail"
when I edit mutt temporary files, e.g., postponed messages. I
traced the problem to mutt's use of mktemp() with the pattern
"muttXXXXXX". I don't know about other OSs, but mktemp() on SunOS
5.8 replaces those Xs with characters from the POSIX portable
filename character set:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
a b c d e f g h i j k l m n o p q r s t u v w x y z
0 1 2 3 4 5 6 7 8 9 . _ -
The pattern used in filetype.vim to match file names of this form is
mutt\w\{6\}
The "\w" character class does not include the characters '.' or '-'.
I replaced that pattern with this one:
mutt[[:alnum:]._-]\{6\}
I was surprised that [:alnum:] worked in the context of an
autocommand filename pattern. I didn't want to use "\f" because it
included too much.
A patch is attached. I have posted it here rather than sending it
to Bram directly to allow others to comment in case I missed
something.
