Subject: PR/55526 CVS commit: src/bin/sh

Module Name: src

Fix a bug that has existed since the "command" command was added in
2003. "command foo" would cause the definition of a function "foo"
to be lost (not freed, simply discarded) if "foo" is (in addition to
being a function) a filesystem command. The case where "foo" is
a builtin was handled.
For now, when a function exists with the same name as a filesystem
command, the latter can never appear in the command hash table, and
when used (which can only be via "command foo", just "foo" finds
the function) will always result in a full PATH search.
XXX pullup everything (from NetBSD 2.0 onwards). (really -8 and -9)
