[Nano-devel] nano 2.3.3 way slower (w/colorization?)

has anyone else noticed that starting with nano 2.3.3, colorized files seem to 
be way slower ?  it seems like nano is constantly refreshing the entire screen 
when it shouldn't.

just enable the default c.nanorc highlighting, then open src/browser.c from 
the nano code base.  try cutting & pasting the first ~20 lines a few times.  
w/nano 2.3.2, it's noticeably faster, and with 2.3.3+, i see the cursor 
jumping around the screen.

might be easier to see if you ssh to a remote system.
