Re: [PATCH] document shell function problems

[Paolo Bonzini]

Here is what I could gather from reports on [EMAIL PROTECTED] In
particular http://www.mail-archive.com/[EMAIL PROTECTED]/msg15966.html
suggested me the following minimal reproducer

  test -n "${ZSH_VERSION+set}" && emulate sh
  failure1 () {
    (exit 1)
    echo $?
  }

Should we add this into m4sh's _AS_DETECT_SUGGESTED_BODY, to skip zsh when
something better is present?

Already there, ac_func_failure fails.  See message I cited above.
