Ctrl-V behavior broken in insert and command modes

[Gary Johnson]

Entering Ctrl-V in insert mode or on the command line used to allow
the following character to be inserted literally. Now, when
I follow Ctrl-V with another Ctrl-V, this sequence is inserted:

^[[27;5;118~

I don't know when this started--I just noticed it in Vim 8.1.2300 on
Linux. I verified that Ctrl-V works correctly in the same terminal
(xterm 330) with Vim 8.0.1453. Both tests were run with "-N -u
NONE".

Here is the output of "vim --version".

This was fixed with 8.1.2350.

If you still need to use 8.1.2300, you can disable the behavior by:

      let &t_TI = ""
      let &t_TE = ""

See `:help modifyOtherKeys` for detail.

Thank you. I updated to 8.1.2352 and, of course, that fixed it.
