Potential Backup bug in 1.2.21

[Luke <..hidden..>]

I just had 1.2.21 email a backup to myself.

The subject of the message was:

LedgerSMB Backup / -1.2.0-20110611.sqlc

The file attachment was called:

-1.2.0-20110611.sql

I have two problems with this.

First, is that the file is obviously binary.  Should it have the sql 
extension?

Second, is it really a good idea to start a filename with a dash?

Obviously, the database name is not being prepended.

For reference, when I do a save to disk for the same backup, instead of 
emailing, the name is:

MyDatasetName-1.2.0-20110611.sqlc

Which is the name it should be given.
