only enable colors when output to a terminal (not to a file)

@sebastianbergmann I'm -1 for this, it doesn't work reliably. For example the jenkins console supports colours using a plugin and not natively.

If people want to turn colours on, let them turn them on rather than saying they can't

I like this. Very hepful on windows. It means I don't need to keep modifying my config each time I clone a repo.

[henriquemoody]

Also it's useful if you want to pipe the output.

[jameshalsall]

I also think this is affecting part of this user's problem #1523

In addition it does not seem to pick up the color="true" setting from our phpunit.xml anymore but that's a different issue.

[GrahamCampbell]

That's unlikely.

[jbladen]

Why not handle this in the same way ls does on *nix systems? Keep the --color flag but use the following arguments, with logical behaviour:

• ‘always’, ‘yes’, ‘force’
• ‘never’, ‘no’, ‘none’
• ‘auto’, ‘tty’, ‘if-tty’

And have it default to "none".

[henriquemoody]

I was thinking about the same thing @jbladen.

[jameshalsall]

@jbladen great idea

Looks like this commit breaks colors display when running on windows in cygwin terminal

[GrahamCampbell]

@Fludimir Lots of things have changed since this.

[Fludimir]

May be, but after update from phpunit 4.3.5 to 4.4.1 colors aren't displayed in console and probably no way to display it.

[GrahamCampbell]

Yeh, try out phpunit alpha, 4.6.x. It's got the new behaviour in.

[Fludimir]

Tried, works only with --colors=always in console. So the only way to display colors in cygwin console will be to manually add this option each run?
