Log:
  Expect :mmap_eof_not_eol to fail

  It relies on a jemalloc feature (opt.redzone) no longer available after
  r319971.

This should be Kyle's bug.

(In reply to Ngie Cooper from comment #2)

Apologies- this completely fell off of my radar. I'm considering ripping this test out. I haven't been able to conceive of a way to test this regression without the redzone support, since it relies on a subtle overflow.

Log:
  Remove t_grep:mmap_eof_not_eol test

  The test was marked as an expected failure in r320414 after r319971's import
  of a newer jemalloc removed an essential feature (opt.redzone) for
  reproducing the behavior it was testing. Since then, no way has been found
  or demonstrated to reliably test the behavior, so remove the test.
