Hello, 

I wrote a patch for header search about a word over two lines. 
Please check it.

For example, following header string contains a word 
splitted into two mime encoded block. It's normal behavior of 
MUAs in CJK environment.

Subject: =?ISO-2022-JP?B?Sk1CGyRCJUQlIiE8JUslZSE8JTkhIRsoQkpBTBskQiVBJWMhPCU/GyhC?=
	=?ISO-2022-JP?B?GyRCITxKWCRHOVQkLxsoQiAbJEI0WjlxGyhCLxskQiVRJWklKhsoQi8bJEIlNSUkJVElcxsoQg==?=

And now, dovecot search command miss to search the word.
    word       : "ABCDE" 
    MIMED      : "AB\r\n\tCDE" 
    search(now): "AB CDE"
     this patch: "ABCDE" 

This patch has a bad side effect that in English or other languages,
two words is connected.

For example, 
> This is a
> sample.
matches to "asample".

I think this is not a big problem, but if there is a good solution,
please let me know.

best regards,
