Fixed format-o in docs/topics/db/queries.txt

It appears that our infamous villain, Significant Whitespace,
has struck again.

In this episode, little Timmy finds himself trapped in a
code well.  He need not despair, however, as Indentation Man
has heard his cries for help and sprung into action.

With his feline helper, Octocat, at his side, Indentation Man
races to the scene, flings open a web-based code editor, and with
terrific aplomb, frees Timmy to be the documentation he always
wanted to be.

Once again Goodness has prevailed.  In the fight for readable
documentation, no stray whitespace will ever be able to
withstand the str.strip()ing nature of....INDENTATION MAN.
