wrap fgets to retry on EINTR
The read() underlying fgets() can be interrupted by a signal handler
causing fgets() to return NULL. Before we started handling SIGWINCH,
the odds of interrupting a read were low and typically resulted in
termination anyway. Replace all fgets calls with a wrapper that retries
in EINTR.
