* lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
whether `set' quotes correctly: redirect stderr of the tested
`set', and use a subshell, for Ultrix; use `sed' instead of
`grep' for zsh `set' which may write binary output; match only
at the beginning of the line, to avoid more false positives.
* doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
