when I use tmpname, I'm expecting a filename which is guaranteed to be unique and that I have
proper privilege to use that file. but I don't know any means to provide some kind of `template'
so that tmpname would give a filename in special format. One can concatenate the name returned by
tmpname with a special suffix, but in theory he lose the guarantees provided by tmpname.

if I want create temporary files with special names, I would usually simply do:

```
local dirname = os.tmpname()
lfs.mkdir(dirname)
local myfile = io.open(dirname .. "/file-with-special-name.specialsuffix", "wb")
--[[ blahblah ]]
```

NOTE: on a windows platform, use ``os.getenv("TMP") .. os.tmpname()`` instead.
