Decreasing the window size crops visible lines

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start mintty -
2. Set the window size to 80x25
3. execute "ls -l /bin"
4. decrease window size to 30x10
5. increase window size to 80x25

I used both the options dialog and dragging the window border to
change the window size. The effect is the same.

What is the expected output? What do you see instead?

I would expect output of ls to be fully visible after the last step.

Instead, the last few lines of output (nr of lines depending on smallest
window height) are cropped to the smallest window width. See below.

I could not discover any way to let mintty show that lost output again.

What version of the product are you using? On what operating system?

$ mintty -v; uname -s -r -m -o
MinTTY 0.3.5

Please provide any additional information below.

It's the same in xterm and rxvt, so I think this is an enhancement request 
rather
than a defect. Rebreaking lines on resize should be possible, but it's a fair 
amount
of work.

Fixed in r216 on trunk: no longer throwing away excess line contents after 
resize.
(Not doing any rebreaking of lines though.)

Reverted fix in r300 on trunk, due to issue 101.
