#5258/#10642: print fn, line, traceback and continue when .pth file is broken
If a .pth file contained an error, it could cause a traceback in site.py,
terminating its processing. In 2.7 and 3.2, the interpreter will then not
start. Previously, a message would print saying to use -v to get the
traceback. In either case, the traceback generated for a failed .pth file did
not include the .pth filename, making it difficult to debug the problem. Now
site.py reports not only the .pth filename but also the line number causing the
error, and just skips the remainder of the file.
