grep: Fixed typo in the README

[ZapAnton]

Basically applies #578 for the grep exercise.

It seems like bob was also updated from the latest problem-specification.

It is a minor change, so maybe it is OK to leave it in this PR?

I plan to merge this on Wednesday unless someone objects.

No, I cannot agree with that. No matter the size of the change, each change should have its own commit so that if I look at the log I can understand why something changed.

I have created #597 . Once it is merged, I request this be rebased so the bob change is no longer in this PR.

[coriolinus]

@ZapAnton I've merged #597; please rebase this against master branch.

[petertseng]

Still awaiting that rebase

(to be clear, the final state should be that only one commit "grep: Fixed typo in the README" appears in https://github.com/exercism/rust/pull/587/commits instead of 22 commits)

I think i messed this one a bit and now cannot find the right solution.

After @coriolinus requested the rebase I pulled the latest changes to master branch, rebased
the grep_update branch (this PR branch) against master, made a pull from remote grep_update
merged the changes and pushed the changes to the remote grep_update. What was the wrong part?

@coriolinus if you have moment, can you give me a hint about a proper steps to finish this PR?
If this takes too much time, perhaps you could close this PR, and I would open another one with more clear changes.

Sorry for the inconvenience.

[coriolinus]

@ZapAnton I've rebased this for you. This is the sequence of commands I used:

git checkout master  # exit the branch I had been on
git pull exercism master  # update master from exercism
git fetch zapanton  # fetch the list of branches you have active
git checkout grep_update  # check out this branch
git rebase master  # rebase against the most current master
git log --graph --decorate --oneline  # demonstrate that there's only one commit past master
git push -f  # force-push the branch to update the PR

[ZapAnton]

Thanks.
Missed the force-push step in my solution
