Unfortunately this is quite a large commit and I haven't looked into the specific change that breaks SIGWINCH handling. --=20 Peter Jeremy --aVD9QWMuhilNxW9f Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAk/0wc0ACgkQ/opHv/APuIfuPQCgkyndvzwlYXBsVF3N55+r1V/P 6pUAn326qQ1i9kI9HkbTHX1Z6mEL/XWv =62+O -----END PGP SIGNATURE----- --aVD9QWMuhilNxW9f--
