This looks like it's an issue with less, which will be the pager that
Git is using. I've just verified I can reproduce it by running
`C:\cygwin64\bin\less.exe C:\cygwin64\var\log\setup.log` from within a
PowerShell terminal, then resizing the terminal; it doesn't need to be
a "snap" to trigger the behaviour.

Somewhat to my surprise, `more` and `vim` don't exhibit this behaviour.
