sed adding a space every time I run it

I am using this to comment out lines that are not already commented out

Code:

sed -i '/^#/!s/\(.*\)/# \1/g' /var/rpi/scripts/display

and this to uncomment the line contaning the word omxplayer-youtube

Code:

sed -i '/omxplayer-youtube/s/^#//g' /var/rpi/scripts/display

The problem is that, every time I toggle this, a space is added to the begining of the line. I worked around this by running:

Code:

sed -i 's/^[ \t]*//' /var/rpi/scripts/display

But its not really a solution.
How can I stop the space from being added to the start of the line?
Thanks

You told it to add the blank character in your first sed.

Fix it.

The comment expression adds the space after the '#', the uncomment expression only removes the '#' leaving the added space.

Fix it by either not adding the space, or by removing the space.
