Fix "Stream has ended unexpectedly" for Name Objects

[speedplane]

Fix a bug which could result in a "Stream has ended unexpectedly" error being raised unnecessarily if a Name object runs right up against the end of a file stream.

I have a test case, but it's unfortunately very convoluted and will be quite difficult for me to get running in PyPDF. However, if one could somehow make a PDF with a inline stream object, and a Name object at the very end of the stream, then it would trigger this bug fix (not sure how to do that).

After staring at that regex in the same function, I also made a few other minor fixes. Don't have a test case for them, but they seem pretty straightforward regex escape fixes. I would bet named objects were not working so well previously.

I had a few PDFs lying around that exhibited this behavior. Fix works well.
