Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
Re-fix open-network-stream responsiveness
Problem reported by Christer Ekholm (Bug#23864).
* src/process.c (wait_reading_process_output): Further fix for
typo introduced in 2015-07-06T02:19:address@hidden when
wait == INFINITY and got_output_end_time is invalid. See:
http://bugs.gnu.org/23864#20
