No, I was quite careful in what I typed. But reading :h modifyOtherKeys
leads me to understand what is going on.

If, when modifyOtherKeys is enabled, instead of:

colon percent s slash percent percent slash ctrl-v ctrl-m slash g enter

I type:

colon percent s slash percent percent slash ctrl-v enter slash g enter

I get the:

:%s/%%/^M/g

output I expect. xterm and vim are trying to represent a <ctrl-m> as
different than <enter> with that setting and I'm seeing the results. But
since <enter> is what I really want, actually using <enter> works.

I'll have to mull over if I consider this an improvement or not.

Why that syntax instead of "set t_TI=|set t_TE="? I'm already using
"set t_Co=0" in ~/.vimrc to disable colors. (Specifically it sets
the number of colors available to zero.) In testing, both forms seem
to work in .vimrc, and neither seems to work from the ":" prompt --
even after I ":!ls" as suggested by the help page.

Thanks for finding that.
