Comment (by niles):
There are a number of other power series bugs that have been waiting in
one way or another for rewriting of padics. Could someone here take a
look and comment on the appropriate tickets? They do not seem to be
resolved by this one.
#9457: Buggy equality of power series -- The fix seems straightforward,
but causes a bizarre doctest failure in `sha_tate.py`
#4656: Power series over p-adics treat inexact zeros inconsistently -- The
fix here causes the same doctest to fail.
#8198: p-adic precision is dropped when matrix acts on vector -- Possibly
a root cause of the previous two bugs.
#5075: Polynomials over inexact rings truncate inexact leading zeroes --
This was somehow fixed for polynomials over p-adics, but polynomials over
other power series still have the issue. David Roe commented that it may
be fixed as part of a larger patch (I hope there's not another one after
this!)
