[Mimedefang] Commas not escaped in MDLOG entries

[Penelope Fudd]

Hi..  I'm writing a program to do stats on the MDLOG entries (similar to
graphdefang), and I noticed irregular data creeping into my results.

It turns out that commas in the attachment filename or subject will show
up in the MDLOG lines in syslog.

This messes up anything that expects a certain number of commas per line
(ie: Graphdefang, my program, other people's programs, etc).

Could you patch mimedefang to defang the log file too?

Thanks!
