Mail: fixed backslash handling in IMAP literals.

Previously, s->backslash was set if any of the arguments was a quoted
string with a backslash character.  After successful command parsing
this resulted in all arguments being filtered to remove backslashes.
This is, however, incorrect, as backslashes should not be removed from
IMAP literals.  For example:

   S: * OK IMAP4 ready
   C: a01 login {9}
   S: + OK
   C: user\name "pass\"word"
   S: * BAD internal server error

resulted in "Auth-User: username" instead of "Auth-User: user\name"
as it should.

Fix is to apply backslash filtering on per-argument basis during parsing.
