I was able to suppress it by adding the argument
--cmd 'set t_cd= t_ce= t_cm=\ t_ve= t_vi='
like this, all on one line:
vim --not-a-term --cmd 'set t_cd= t_ce= t_cm=\ t_ve= t_vi=' --cmd 'echo
v:versionlong|quit'
That clears the values of all those escape sequences in the output.
Vim loudly complains if the t_cm sequence is empty, so I just set it
to a space.
It seems to me that the --not-a-term option is not doing everything
it should if Vim outputs terminal escape sequences when no terminal
is supposed to be there.
