thank you Richard for all the helpfull commentgs. The reason why I did not
use M-; is because I wanted 3 comment symbolsd at the begining of the line
that way "tab" does not put these particular comments in the middle of the
buffer. the other function I built becaause I did not want to highlight
the region. so it does the indentation and stays where the cursor was
before the command was issued.
