Subject: Ensure all backends _remember_ the connection has closed after
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/7dbb9f565cd73e01515dadd6825c3cd0322b9783

Ensure all backends _remember_ the connection has closed after
receiving a network error. Should prevent the cascading-error-box
bug.
