My Accepted solution 8202681 for problem 1050 gives incorrect answer on my test (test contains command '\endinputany' in the middle of text).
Please add my test to test package.

     TEST:
There is no "q in this sentence. \par
"Talk child," said the unicorn.

\endinputany
She s\"aid, "\thinspace `Enough!', he said."
\endinput

     INCORRECT ANSWER:
There is no q in this sentence. \par
``Talk child,'' said the unicorn.

\endinputany

     CORRECT ANSWER:
There is no q in this sentence. \par
``Talk child,'' said the unicorn.

\endinputany
She s\"aid, ``\thinspace `Enough!', he said.''
\endinput

This is a good test, but I find it somewhat contradictory to the spirit of the problem. I added a note to the statements: "You may assume that there are no other commands starting with the prefix \endinput."
