It's a bashism, but is surprisingly easy to do and costs very little code.

Declare the variable in the scope it is used rather than the entire
function scope so it's obvious it is only used there.

hush: implement type
...
Implement support for the POSIX `type` command. Only POSIX stuff is
supported here, no bash extensions like -p or -P.
In the process, split the $PATH searching code out of builtin_source() and
into its own find_in_path() function so we don't duplicate it.
