This replaces --with-curses-terminfo with --with-term-lib="LIBS" and
documents the position, apparently for the first time.

See chapter 5 in the FAQ for some notes on multibyte input.
+Historically, several different libraries have provided the features the
+shell needs to provide output to the terminal. The most common have been
+termcap, which is now largely outmoded, and curses, which supersedes
+termcap and typically contains the same features as well as others.
+configure will search for an appropriate library; the default search order
+is "tinfo termcap ncurses curses" except on HP-UX and Solaris where it is
+"Hcurses ncurses curses termcap". Note that even though termcap is usually
+searched first, zsh tries to make features from curses available and if the
+curses library contains both curses and termcap features, as is normal,
+the curses variant is used. ncurses is a newer version of curses
+and tinfo is related to it.
+On some systems a suitable development package with a name such as
+curses-devel or ncurses-devel needs to be installed before zsh can
+be compiled. This is likely to be contained on any installation media,
+or available for download. It is highly unlikely that you will need to
+compile this from scratch.
+You can tell configure which libraries to search by passing an
+argument via --with-term-lib. This can take a space-separated list
+of libraries to try, so the default is equivalent to
+--with-term-lib="tinfo termcap ncurses curses". This replaces the
+old option --with-curses-terminfo, which altered the search order but
+didn't allow an explicit search list to be passed.
