    which: Use size_t instead of ssize_t for pathlen
    
    The "pathlen" variable is the return value of strlen(3) and is then
    passed as an argument to malloc(3) and memcpy(3). The size_t type
    matches the prototype for these functions. The size_t type is unsigned
    so it can fit larger $PATH values than ssize_t. However, in practice
    ssize_t should be larger enough so this change is just for clarity.
