-												Do not ignore eof in expect tests

expect_after that adjusts default timeout handler, reseted eof handler,
and this tell expect that it can ignore eof from read, consider the
following example:

<details>

    ```expect
    #!/usr/bin/expect -f

    exp_internal 1
    log_user 1
    set timeout 4
    match_max 100000

    expect_after {
        # eof { exp_continue }
        timeout {
            exit 1
        }
    }

    spawn bash -c "sleep 1; echo ':) '"
    expect ":) "
    ```

    ```
    $ ./expect.expect < /dev/null
    spawn bash -c sleep 1; echo ':) '
    parent: waiting for sync byte
    parent: telling child to go ahead
    parent: now unsynchronized from child
    spawn: returns {6614}

    expect: does "" (spawn_id exp4) match glob pattern ":) "? no
    expect: read eof
                 ^^^
    expect: set expect_out(spawn_id) "exp0"
    expect: set expect_out(buffer) ""
    ```

And with uncommented eof handler:

    ```
    $ ./expect.expect < /dev/null
    spawn bash -c sleep 1; echo ':) '
    parent: waiting for sync byte
    parent: telling child to go ahead
    parent: now unsynchronized from child
    spawn: returns {17959}

    expect: does "" (spawn_id exp4) match glob pattern ":) "? no
    expect: read eof
    expect: set expect_out(spawn_id) "exp0"
    expect: set expect_out(buffer) ""
    expect: continuing expect after update

    expect: does "" (spawn_id exp4) match glob pattern ":) "? no

    expect: does ":) \r\n" (spawn_id exp4) match glob pattern ":) "? yes
    expect: set expect_out(0,string) ":) "
    expect: set expect_out(spawn_id) "exp4"
    expect: set expect_out(buffer) ":) "
    ```
