This is what I got with line 85 (the slow one):

% time vim -u ./vimrc --noplugin +85 -c 'norm! o' -c 'q!' foo.py
0.17s user 0.00s system 63% cpu 0.277 total

% time vim -u ./vimrc --noplugin +85 -c 'norm! o' -c 'q!' foo.py
0.14s user 0.03s system 63% cpu 0.272 total

% time vim -u ./vimrc --noplugin +85 -c 'norm! o' -c 'q!' foo.py
0.16s user 0.02s system 62% cpu 0.275 total


And this is for line 87 (the fast one):

% time vim -u ./vimrc --noplugin +87 -c 'norm! o' -c 'q!' foo.py
0.05s user 0.01s system 98% cpu 0.057 total

% time vim -u ./vimrc --noplugin +87 -c 'norm! o' -c 'q!' foo.py
0.05s user 0.00s system 32% cpu 0.149 total

% time vim -u ./vimrc --noplugin +87 -c 'norm! o' -c 'q!' foo.py
0.04s user 0.00s system 30% cpu 0.146 total


Visually I can tell that the second line executes faster than the
first one. Also note that I used 'o' and not 'O'. With 'O', line 87
takes more time but is still faster than line 85. There's not much
difference for line 85.
