IMAP resilience under Unix line-endings

[Uday Reddy]

IMAP mail retrieval failed in vm-retrieve-real-message-body, when the Cygwin SSL implementatioin gave warning. Should it be more resilient?

  Preferred POSIX equivalent is: /cygdrive/c/Users/udr/AppData/Local/Temp/vm162022099
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
