I'm glad to see you've been editing these.  I believe these two sentences that remain in the article were

a) written by me, and
b) seriously wrong.

"The earliest Lisp macros took the form of FEXPRs, function-like operators whose inputs were not the values computed by the arguments but rather the syntactic forms of the arguments, and whose output were syntactic fragments to be used in place of the FEXPR's use. In later Lisps, FEXPRs were replaced by DEFMACRO, a system that allowed programmers to specify source-to-source transformations that were applied before the program is run."

Anyone want to fix these?
