Subject: Improve window-size handling in Unix Plink.
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/putty/commitdiff_plain/679db5850a18040c653f8edc403dc0bd86eb07c9

Improve window-size handling in Unix Plink.

Unconditionally override the configured terminal size with the one
from stdin if it's available.  This avoids the silliness whereby if
Default Settings had a terminal size set, Plink used this and thus
caused the server to use the wrong size.
