Here is a slightly better keyboard macro to record.  Go underneath
the line that you want to incrementally copy and do (spaces inseted
for readability)

C-x( C-e C-p C-M-s \< C-<space> C-M-s C-s M-w C-n C-y C-x)

IOW, go to the end of line, go to the line above, search for
beginning of word, set the mark, find the next beginning of word,
copy region, go to next line, yank.  Now hit C-xe to copy the word
above and (in emacs22 at least) keep hiting "e" to repeat as many
times as desired.  Haven't thoroughly checked it but it should work.

Shouldn't be hard to write this in lisp, either.
