Regex support for file names

If I have three files with the following names:

```
Show.S03E01.720p.The_episode.mkv
Show.S03E02[720p]_Another.mp4
Show.S03E0304-HDTV.mkv
```

I want to save them with the command:

``` bash
put save "^Show.*"
```

or something on the similar lines.

Instead of,

``` bash
put save Show.S03E01.720p.The.episode.mkv Show.S03E02[720p]_Another.mp4 Show.S03E0304-HDTV.mkv
```
