'Format Code' does not delete trailing spaces

[matsu]

1. Spaces after letter are not deleted.
2. If there is a cursor, blank line spaces are not deleted.

I made the script to remove the garbage from file after the AIDE editor:

cat $SRCFILE | expand -t4 | sed -r “s/\r+//” | sed -r “s/ +$//” > $TMPFILE
mv -f $TMPFILE $SRCFILE
