SVN rev 214304 on 2010-10-24 22:03:21Z by jilles
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.)
Exp-run done by: pav (with some other sh(1) changes)
