I don't know what would break for sure, but I imagine that code which
has never before received any "(y or n)" prompts would not know what to
do when it got one, for any operations it conducted on behalf of the
user. This is the sort of thing that causes tests in the testsuite to
time out. The other likely problem is with line buffering; output over
a pipe is on many platforms block buffered rather than line buffered,
and the prompts might fail to show up when they were needed.
This is all speculation! Maybe it would just work, but it doesn't seem
like a great change unless someone who thinks it's a good idea
volunteers to test a bunch of different scenarios, and I'm not that
interested in the issue, I'm afraid.
