[Remind-Fans] `make test` leaves processes around

[Mike Kelly]

Hi,

Running `make test`, with the current git at least, seems to leave 2
running remind processes around after it has finished, but detached
from the tty.

Aside from the wasted resources, the way that these are left around
also causes problems at least for the package manager I use, paludis,
because I think it's essentially waiting for its child to terminate,
but these two children aren't terminating. Essentially, it leads to the
install process hanging indefinitely.

The processes that are left around:

    103      31049  0.0  0.0   6584   108 pts/1    S    11:34    0:00 ../src/remind -gaaa - 1 Jan 2000
    103      31052  0.0  0.0   6584   108 pts/1    S    11:34    0:00 ../src/remind -gaaad - 1 Jan 2000

Those seem to correspond to this bit in tests/test-rem:

  echo "Sort Test" >> ../tests/test.out
  (echo "REM AT 12:00 MSG Untimed"; echo "REM MSG Timed") | ../src/remind -gaaa - 1 Jan 2000 >> ../tests/test.out 2>&1
  (echo "REM AT 12:00 MSG Untimed"; echo "REM MSG Timed") | ../src/remind -gaaad - 1 Jan 2000 >> ../tests/test.out 2>&1
