As I (think I) said, I use (if (or cond cond) then else), if THEN is a single
sexp.
If THEN is not a single step I don't bother to use
(if (or cond cond) (progn THEN1 THEN2...)) else).

BTW, for transforming sexps with `not', `and', and `or', for readability
or for performance reasons, I sometimes use `notandor.el'.

Also, package `el-search.el' has similar possibilities (and many other
good things).
