Suite only not anchored to title start

[ScottFreeCode]

In the process of looking into #2157 (comment), I noticed that the BDD interface's it.only escapes the regular expression and requires it to match the whole title with ^ and $, but describe.only merely passes the string to grep, which escapes it but does not require it to begin with ^. This same issue also affects the QUnit and TDD interfaces.

Contrived example:

describe.only("one", function() {
  it("two", function() { /* succeed */ })
})
describe("you know", function() {
  it("one of these should not run", function() {
    throw new Error("Specifically, this one should not run!")
  })
})

Something similar goes for the links in the HTML reporter; the test ones should use ^ and $ to require matching the whole title, and the suite ones should use ^ to require matching the start of the title. (Note that this code is in the same area as #2285 and #2300.)

@ScottFreeCode I merged 8a75434 into v3.0.0 branch. does this solve the issue?

Sorry I missed this!

Making only programmatic resolved the primary issue here.

It looks like the HTML links still have the same sort of problem, however. Do we have another issue for it? If not, I will open one instead of keeping this issue open for it.
