+TODO list for ex
+
+- Some support for UTF-8 combining characters should probably be added.
+
+- Since the POSIX standard developers did not include a method to
+    determine whether something is a valid collation symbol or an
+    equivalence class, and since there is no access to the basic
+    collation sequence, LC_COLLATE locales are completely ignored.
+
+- There may be other unresolved POSIX.2 demands I did not notice yet.
+    Please write me if you find one. You can get SUSv2 from The Open
+    Group <http://www.UNIX-systems.org/> for $0, it contains nearly the
+    same text for ex/vi as POSIX.2 and is a good reference manual.
+
+- SVr4 ex probably has some silent features that this one should have too.
+
+- SUSv3 / POSIX.1-200x ex/vi support.
+    I did not yet decide whether this is worth implementing. It requires
+    a lot of mostly small changes that make vi more nvi-like in general.
+    If SUSv3 has as little success in the Open Source world as its
+    predecessors, it might be better to ignore it and stay on the
+    officially obsolete SUSv2 / POSIX.2 level.
+
+- The traditional regular expression code in ex_re.c could be updated to
+    work with multibyte characters. This would mostly involve to take the
+    code from libcommon/regexp.h of the Heirloom Toolchest.
+
+- Translated message catalogues.
