Oh, I see what's going on: the filling only reindents the lines after
the first (i.e. only the lines that come after a newline inserted by the
filling code), and the filling code simply trusts the first line to be
properly indented.

I think so; in particular, text at the top level not containing
latex commands should have the same filling rules as text in text mode.

I think there is something else going on; that paragraph was
contained in absolutely no environment. As an experiment, I indented
the first line only of the original paragraph by 20 spaces. The result
was that the entire paragraph is indented 20 spaces. I can't think of
any argument for why this makes sense.

So you're saying that filling should not use indentation when filling
top-level text and that would solve your use case?
Hmm... I see some problems with that:
- your original message reported that the whole paragraph was indented
(apparently by 4 spaces), so either that paragraph was not "outside
of any environment" or there is something I don't understand.
- that would introduce unexpected difference between otherwise similar
circumstances (top-level or not-top-level text).

Yes, I don't think we can satisfy everyone without someone having to do
some extra configuration to express his preference (which is what
fill-indent-according-to-mode is for).
But I could offer another "way out", based on your example text: the
indentation code could potentially be modified to try and recognize
paragraph-beginnings and indent them by some extra N spaces, so as to
look like:
This is a sample paragraph of text that is long enough that it
may need to be filled. Here's a second sentence to continue the
paragraph. And one more sentence for good measure.
I personally wouldn't like it, so it would still need to be controlled
by some configuration variable. And I'm not sure it could be made
reliable enough.

I tend to view latex as text with intermixed code so I see this
differently. I can see an argument for why text inside of a specific
environment might need to be indented specially, I don't see why that
would apply to top-level text outside of any environment.
I suspect we're going to agree to disagree on this one; feel free to
close this bug.

It's a feature if you consider LaTeX as code rather than as text, so you
want the text parts of the LaTeX code to be properly indented, like
any other.

While that workaround does work, I'm still not convinced this isn't
a bug. Why is this broken behavior a feature?

It's not a bug, it's a feature. The change is because Emacs-21 did not
offer indentation for LaTeX, whereas Emacs>=22 does.
To get the behavior you want, you'll want to set
fill-indent-according-to-mode, e.g.
(add-hook 'latex-mode-hook
(lambda ()
(set (make-local-variable 'fill-indent-according-to-mode) nil)))

To reproduce the bug, paste the following text into a new .txt file:
==================== cut here ====================
This is a sample paragraph of text that is long enough that it may
need to be filled. Here's a second sentence to continue the paragraph. And one more
sentence for good measure.
==================== cut here ====================
If you request justification via esc Q, the paragraph is reformatted to:
This is a sample paragraph of text that is long enough that it may
need to be filled. Here's a second sentence to continue the
paragraph. And one more sentence for good measure.
Repeat the steps using instead a suffix of .tex (latex mode); this time
you instead obtain the following incorrect result:
This is a sample paragraph of text that is long enough that it may
need to be filled. Here's a second sentence to continue the
paragraph. And one more sentence for good measure.
Justify in latex mode worked correctly in Emacs 21, but does not work
correctly in 22 or 23. Please fix.
