Subject: extindex: enable autoflush on STDOUT/STDERR
X-Git-Tag: v1.7.0~1484
X-Git-Url: http://www.git.stargrave.org/?p=public-inbox.git;a=commitdiff_plain;h=41464d205ade16a5a847061fa2eb706a33b52a88

extindex: enable autoflush on STDOUT/STDERR

With --watch, the output may be redirected to a pipe or socket
which Perl may decide to buffer.  Ensure Perl doesn't buffer
these outputs since they can provide real-time status updates
in response to signals or FS activity.
