LINES and COLUMNS are legacy mechanisms which may serve as a workaround 
if the system doesn't otherwise handle screen size changes properly. 
They should not be needed on modern systems where the tty driver 
maintains the information.
(You may note that mintty has not set them initially but they get set on 
resize - by whatever means... - while in a cygwin console they are not 
used at all.)
So if you happen to have these variables set on a system which does not 
maintain them, they don't get changed on resize and confuse your 
environment. In most cases the best remedy is to just unset them - does 
that help?
