[Rspec-devel] experimental output tweak

[aslak hellesoy]

On Rspec trunk the default output will now look like:

--------------------------
..........................

The dashes are printed before the specs are run, and it represents the
total number of specs. It can be useful if there are many (slow) specs
to see how much is left

I'm not sure I like it though - it's noisy, and specs should be fast,
in which case it's not really needed. But in Rails things tend to be
slow.

Anyhow - the underlying change opens up for better progress reporting
for other reporters, such as Dave's cocoa runner/reporter. I will also
need it in my upcoming port of TDDMate (BDDMate).

If people don't like this for the textual output we can easily remove it.

wdyt?
