bugfix: lib/sh/util.sh: recursive aliases (i.e. aliases that call a command of the same name): use "" around the command name so it isn't reexpanded if the function using the alias is copied using copy_func(). (aliases will be reexpanded every time a function is redeclared since they appear unquoted in the function definition.) this is a bug in `declare -f` for which there is no fix, necessitating the "" alias workaround instead.
