Don't include DeleteLine in progress length

[eatkins]

I incorrectly included the DeleteLine in the progress line length and
this could cause certain progress lines to be incorrectly reported as
multi line when they actually fit on a single terminal line.

[warn] /home/travis/build/sbt/util/internal/util-logging/src/main/scala/sbt/internal/util/ConsoleAppender.scala isn't formatted properly!

[eatkins]

doh!

Wouldn't it still be off if the original line contained some color stuff?

[eatkins]

Yes, but why would the task name have color though? Is there an api that would tell you the printable length of a string including escape sequences? I think this is a reasonable approach that is better than the status quo. A more robust solution would be welcome though.

oh I thought it's for log lines. For task names this should be ok.

Not sure how performant it is but there used to some code in sbt 0.13 - https://github.com/sbt/sbt/blob/v0.13.18/util/log/src/main/scala/sbt/ConsoleLogger.scala#L148-L150

If I get a chance, I'll take a look at that.
