Stil a verbiage?

"Lets" -> "Let's".  "Let's clarify the one-line summary."
Similarly, 

    The one-line summary for 'git hash-object' can mislead hasty
    readers to think that the command can only be used to ...

or something, perhaps.

What is this older version of the proposed log message?

Not a new problem, but as we are updating the one-line summary,
perhaps we should also do "creates" -> "create" to match "Compute".

Not a new problem, but "-t <type>" alone is clear enough that it
specifies something called "type" already.  If we are to explain
it further, we should at least say something about the significance
of that "type" thing.  Perhaps "Specify the type of the object to be
created" or something?

Thanks.
