 Modified Files:
 	src/bin/sh [netbsd-8]: exec.c
 Log Message:
 Pull up following revision(s) (requested by kre in ticket #1629):
 	bin/sh/exec.c: revision 1.54
 PR bin/55526
 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)
