Hallo maintainer,
fetchmail break messages with '.' character at 1st column of mail body.
It sometimes happens receiving mails from MS Outlook where line is
wrapped just before last dot in a text paragraph. Affected message
is cut to delivered and undelivered part. Cut position is at the
described dot, start of message is delivered and the rest disappears.
No error message is issued to user.

How to reproduce this bug:
No MS tools are neccessary to simulate problem. You can simply compose
a message similar to the following and send it as plain text to a mailserver.
Then fetch this mail via fetchmail (tested with POP3 protocol) and show it.

-------
Sample message. This message wil be partially delivered.
Cut point is here:
..
This part of message will never be delivered by fetchmail
-------

Changing fetchmail to another package, e.g. mpop leads to delivery
of whole message.

Thank you for your help,
  Pavel Vavra
