+ init.sh: penalize a set-x-impaired shell; don't disqualify it
+ * tests/init.sh: Too many shells corrupt application stderr when
+ you set -x, so we can't afford to disqualify them, since at least
+ on Irix-6.5, that would disqualify all bourne shells.
+ Instead, use a two-pass approach.
+ On the first pass, try to find a shell that meets the stricter
+ condition that set -x does not corrupt stderr.
+ If no shell meets the stricter condition, retest each candidate
+ shell, but without that extra condition. Finally, when
+ VERBOSE=yes is requested and set -x might cause trouble, simply
+ issue a warning and refrain from enabling debug output.
