bug#21324: 24.5; Emacs Term Scroll Region not Reset

[Guillaume Koenig]

Hi. I find it useful sometimes to fire up ansi-term, ssh into a remote
server, and do light editing with vim. It works well. The issue comes
after exiting vim : the scroll region set by vim is still active. Any
further output of the terminal is limited to the last screenful of
text. This renders it useless for scrolling back in the buffer. Edebug
shows that `term-scroll-with-delete' is set when entering vim, but not
reset on exit (it behaves that way locally too). Thank you for emacs.
