With tab characters in the log, the user has to only enable csvlog to 
have both machine and human readable logs. The user can use the csvlog 
always and use it for human reading and load it into the database only 
if he wants it for further analysis. That was my original intention anyway.

(Also as I wrote the patch some time ago, I forgot how the loaded log 
gets displayed after a select. If it gets displayed with the tabs, then 
isn't it desirable that way as well?)
