274561 - the to-line is not correctly representet by moz-mail 1.7.3

Status: RESOLVED DUPLICATE of bug 254519

(SeaMonkey :: MailNews: Message Display, defect)

Description

[chris]

when receiving a mail with a to-line like this:
To: =?iso-8859-1?Q?Fa=2E_St=FCrtz=2C_Engel?= <[e-mail]>

Mozilla 1.7.3 does something like that out of it:
"Fa. Stürtz", "Engel <[e-mail]>"
so you got 2 addresses out of one!
the correct interpretation would be:
"Fa. Stürtz, Engel <[e-mail]>"
(only one address)

Best regards,
Christof Engel, [e-mail]

Problem was re-created with Mozilla Suite latest-trunk 2004121305(Win-2K).
Re-creation procedure.
 (1) Create a draft mail (Compose a mail and save in Drafts)
 (2) Terminate Mozilla(both browser & mailnews)
 (3) Edit "Drafts" file by text editer,
     change To: header to
      To: =?iso-8859-1?Q?Fa=2E_St=FCrtz=2C_Engel?= <[e-mail]>
     and save file
 (4) Delete "Drafts.msf"
 (5) Retart Mozilla
 (6) See the draft mail, then "Edit Draft"
     => To: is splitted to two recepients

This problem did not occur when "\"(=5C,escape char) is inserted before ","(=2C), 
     To: =?iso-8859-1?Q?Fa=2E_St=FCrtz=5C=2C_Engel?= <[e-mail]>
although another problem occurs.
  - Display becomes Fa. Stürtz\\, Engel
    Special data was displayed(escape char in this case).
    This is already reported problem.
(Sorry but I'm not familiar with Quoted Printable.                         )
(So I don't know whether result of inserting "=5C" only is valid QP or not.)

I can not say RFC 2822 says which, "," in atom should be escaped, or no need of
escaping.
