Oh yes, you are right. I should not trust my memories but look into the man 
page first. :-(

But if you do it your way you have the problem that sed is reading from the 
file on the disk and writing to the disk again. If you want to use sed more 
efficiently with Quanta you better use is as a filter, reading from stdin and 
writing to stdout. This way Quanta can pipe the content of the current editor 
through it and would not work with the file on the disk.

But this _is_ wrong ;-) If you want to give an external file you would use -f 
and -e is to give the expression as argument directly.
