sh: Do not allow overriding a special builtin with a function. This is a syntax error. POSIX does not say explicitly whether defining a function with the same name as a special builtin is allowed, but it does say that it is impossible to call such a function. A special builtin can still be overridden with an alias. This commit is part of a set of changes that will ensure that when something looks like a special builtin to the parser, it is one. (Not the other way around, as it remains possible to call a special builtin named by a variable or other substitution.)

sh: Fix some tests that used sh instead of ${SH} so they tested the wrong sh. This was caused because these tests were committed after the sh -> ${SH} change but were created before. 2010-12-12 16:18:16 -05:00			`${SH} -c 'unset() { echo overriding function executed, bad; }; v=1; unset v; exit "${v-0}"' 2>/dev/null`
