Python API: Fix an exception when registering a global pretty-printer in verbose mode

  This patch fixes a Python exception that was being thrown when trying to register a global pretty-printer with verbose mode on:

  File "/usr/share/gdb/python/gdb/printing.py", line 119, in register_pretty_printer
    gdb.write("Registering global %s pretty-printer ...\n" % name)
NameError: name 'name' is not defined

My copyright assignment is on the works, but since this is a small patch I don't think it's necessary.

Hi.

LGTM with one nit:
I suspect the patch as is will go past our 80 character hard limit.
[Though PEP008 has a 79 character limit ... yay.]
While in C we would put the '%' on the next line, I think we follow
the opposite convention in python. That's what the surrounding
code does anyway, so move printer.name to the next line.

And, yeah, small enough to not need a copyright assignment.

Thanks!

Will do.
