My emacs (20.7 --- bang up to date?) doesn't have them either. However,
google is a fabulous resourse:
gg:delete-trailing-whitespace
gives
http://www.unixguide.net/unix/sedoneliner.shtml
# delete trailing whitespace (spaces, tabs) from end of each line
sed 's/[ \t]*$//' # see note on '\t' at end of file
where \t is a tab.
and
gg:emacs delete-trailing-whitespace
gives
http://www.dotemacs.de/emacro/emacs/functions.html
which contains the magical expression.
So now my question becomes, how do I modify my .emacs to load this file in
c-mode and in c++-mode and how do I follow Lars' example and have it on by
default. Lars"?
