It didn't seem that bad to me. One problem is to not select, eg,
<readline/readline.h> in preference to <editline/readline.h> if we've
selected libedit for linking to. (I think that is the behavior that
bit Russ.) But that seems a small matter of paying attention to a flag
variable set by PGAC_CHECK_READLINE. The other problem is that if we
select <readline.h> we can't really be sure it matches the selected
library. I'm not sure that we *need* to solve that --- if you have
readline.so and not <readline/readline.h> then <readline.h> had better
be the right thing. But I would think it could be done with some
appropriate AC_EGREP_HEADER check if you wanted to be paranoid.
