1. Only read the first 1024 bytes of the file. The RUN: lines should all be
within that amount of space. This keeps I/O costs down when reading
very large files.
2. Print PR numbers with a PR prefix so it is clear what they are.

More improvements:
1. Using ::errorInfo wasn't such a hot idea. Go back to just printing the
offending line of code and the stderr output. This is sufficient and
not entangled with Tcl goop.
2. Capture the problem report numbers and report them whether pass or fail.
This helps quickly get some context when a test fails, if it has an
associated PR number.
