[bug-mailutils] [imap4d] r/o file in $HOME

[Linus Nordberg]

Hi,

EXAMINE'ing a readonly file makes imap4d on FreeBSD send the client
the following strings before the ordinary answer is sent.

  imap4d in free(): warning: chunk is already free
  imap4d in free(): warning: chunk is already free

In fact, that is the behaviour the first time the client EXAMINE's.
The second time you get four identical lines, the third time four
lines again.  If you chmod 600 foo, the next EXAMINE gives you two of
the above lines, the next time zero lines.

1) stderr shouldn't go to the client
2) imap4d shouldn't free more than once

Details can be found below.
