Fix memleak when we search for the existence of a given external program. For each program + path in env this code is run, and before this, the full location tried was not being freed, causing a nasty li'l leak when a lot of alternatives are tried and the $path is heavy. Well, all leaks are nasty but in such a case it's a lot of nasty instead of a lil freaky or somethin' Will forport this to head if I find the leak there as well.
