Ignore beautifulSVN when redirect output in file

[4wk-]

When you use beautifulSVN, term output looks great, but when you redirect it to, let's say, a file, the interpretated char (used for colors) are presents in the file.

Example:

$ svn st > a
$ vim a
^[[36mM       path/to/modifiedfile.txt^[[00m

As you can see, the cyan M is encircle by special chars.

It could be great if beautifulSVN could guess if, when called, it will be display on standard output, or redirected to a file.
