Subject: su: explicitly enable echo for --pty
X-Git-Tag: v2.37-rc1~97
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=497c61f7b038ee7e0b776c3f3dfb3c31ede1a148;p=thirdparty%2Futil-linux.git

su: explicitly enable echo for --pty

Since 75ccd75a2fa1194c6415c47b0024a438e26f1ad7 we need to explicitly
set echo flag by ul_pty_slave_echo(pty, 1).
