Summary: support whence argument for GzipFile.seek (bug #1316069)
Initial Comment:
This adds support for whence=0 and whence=1 to the GzipFile
seek method. See
www.python.org/sf/1316069
for background.
Open questions:
Q: can/should whence=2 be supported?
Q: if not, should whence=2 give an IOError or a ValueError
Q: can patches be attached to bug reports?

I think whence=2 can be supported, but shouldn't be. For
reading, only negative offsets would be meaningful, and they
can be supported the same way as they currently are (i.e.
read all over). For writing, whence=2 would have no effect.
seek apparently always gives a value error (e.g. also
file.seek, for whence=10), so it should do so also here.
Patches can be attached to bug reports if you are a patch admin.
The patch lacks documentation and test case changes.
