I believe the command below was wrapped to two lines due to the cms software.  If I am not mistaken it should be one line unless you explicitly spit it using the "\" (backslash).

 For those new to the command line, note how the prompt changes for the second and third lines, indicating the command is continued across multiple lines:

 foo@foobar:~$ fakeroot make-kpkg --initrd --append-to-version=-custom \
> kernel_image \
> kernel_headers
