 KNOWN BUGS IN ZSH
 -----------------
 
+On some terminals, display of lines with exactly 80 characters is
+problematic.  zsh assumes that the terminal does not print an extra
+newline in this case, but some terminals (e.g. aixterm) do.
 ------------------------------------------------------------------------
-Completion has a habit of doing the wrong thing after a
-backslash/newline.
+When interrupting code like the following with ^C:
+  while true; do
+    sh -c '...'
+  done
+if the `sh' is executing, zsh does not know that the sh received a ^C and
+continues with the next iteration.  This happens for any program which
+handles the interrupt, then exits after tidying up; it does not happen for
+zsh, which exits directly from the signal handler.  The workaround is to
+use ^Z which forks the shell and makes the loop a separate job, then kill
+the suspended loop.

 The pattern %?* matches names beginning with %? instead of names with at
 least two characters beginning with %. This is a hack to allow %?foo job
 substitution without quoting. This behaviour is incompatible with sh

 such patterns unchanged if they do not match regardless of the state of

+Numeric ranges are still too greedy with using characters; for example,
+<1-1000>33 will not match 633 because the 633 matches the range.  Some
+backtracking will be necessary.
