>Description:
basename(3) returns a pointer to an internal static buffer. Therefore,
a copy of this string should be made if you make multiple calls to
basename(3). resize(1) does not, and we get:

```
$ resize blah
Usage: bash [-v] [-u] [-c] [-s [rows cols]]
$ 
```

Here, `bash' as the name is the result of the _second_ call to basename
in the source.
>How-To-Repeat:
As above.
