for the third:
/\+\+[a-zA-Z_]+[0-9a-zA-Z_]*/{
x/\+\+/d
a/++/
}
the braces stuff is pretty tough, but maybe someone will have an idea.
however it is really easy to do it by hand in acme.
click on the inside of the opening paren with a double click then click
button 2
(while still holding down button 1 from the double click) this will cut
everything
inside that and the matching paren. then highlight the remaining () and
while
still holding down button 1 push button3.
Looks complicated written down but it's a really quick and easy to learn
sequence.
