Reverted [d156af9fb76dd2f4] and removed tests io-52.20 io-75.6 io-75.7, as this

commit, intended to fix issue [b8f575aa2398b0e4], breaks the semantics of
[read] and [gets].  Such a change would require an accepted TIP. See [b8f575aa2398b0e4] for further discussion.

jn: @pouryorick See [b8f575aa2398b0e4] for the reason why this commit is not appropriate: It gets core-8-branch back in the buggy state it was, without even providing a real solution everyone agrees on. You shouldn't revert my patch just because I reverted yours.

pooryorick:  As I explained, the reason for this reversion is that it hard-codes an unapproved change in the semantics of [read] and [gets] into the test suite.  Jan, your statement that it's a "revenge" reversion is false.  I spent a month trying to find some alternative to this reversion before actually performing it.  A commit that codifes in its tests changes in semantcs to [read]/[gets] simply shouldn't be on core-8-branch.
