[bug-mailutils] mu_mimehdr_aget_disp() bug

[Kostik]

Hi All!

In the last updated mimetest.c:

if "Content-Type" contain only type without name and without semicolon(;)
at the end, then mu_header_sget_value() already return type. But
mu_mimehdr_aget_disp() return NULL.

Example:
---
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
 filename="=?utf-8?B?0JrQvtC80LzQtdGA0YfQtdGB0LrQvtC1?=
 =?utf-8?B?IA==?=
 =?utf-8?B?0L/RgNC10LTQu9C+0LbQtdC90LjQtQ==?= (NewPro).docx"
---

* hvalue=application/octet-stream
* type=(null)


But if (semicolon is here ------------v):
---
Content-Type: application/octet-stream;
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
 filename="=?utf-8?B?0JrQvtC80LzQtdGA0YfQtdGB0LrQvtC1?=
 =?utf-8?B?IA==?=
 =?utf-8?B?0L/RgNC10LTQu9C+0LbQtdC90LjQtQ==?= (NewPro).docx"
---

* hvalue=application/octet-stream;
* type=application/octet-stream
