Well, I agree with Dan Nicolaescu that these functions are not so useful.

trim-defines seems to have a very specific usage.

untrim-lines only adds ^M at end of each line.
It seems the only usage should be to deal with CR LF for Windows text files,
probably when Emacs didn't deal with end of line depending on the 
environment,
that is, a very very long time ago.

All other functions are already implemented in whitespace.el,
except trim-spaces which seems to be a variant of just-one-space function.
