+Subject: [PATCH] pv/display: handle error of tcgetpgrp() in pv_in_foreground()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Show pv progress bar even if no terminal is set, e.g., in a busybox
+init script. The description of pv_in_forground() states it will
+return true "if we aren't outputting to a terminal". However, this
+is not the case since tcgetpgrg() will return an error and set ERRNO
+to ENOTTY if the output fd is not an tty. We now handle this error
+correctly and pv_in_foreground() returns also true in that case.
