autoindent, smartindent, cindent all make pasting work as if nopaste was turned on

[t-ye]

For this plugin to work, it appears that all types of automatic indenting must be off, i.e.,

 set noautoindent
 set nosmartindent
 set nocindent

must be in your .vimrc. (Not sure if any type of automatic indenting affects the other.)¹ Checked both in and out of tmux.

I realize this was addressed in #2, but I'm hoping it's possible to add an "automatic indentation toggle" to the plugin. I like some automatic indenting, and it doesn't really save any time if I have to call set noautoindent and set autoindent every time I paste.

^{1. I did a bit of experimentation with set paste and noted that set paste followed by set autoindent (or either of the other two automatic indenting settings) still broke pasting, with or without this plugin, even though I was still in paste insert mode. So it seems that set paste may just do the above disabling of automatic indenting (among other things) and we can break it be re-enabling them.}

I don't have any of those in my ~/.vimrc and this plugin works.

@t-ye, this plugin programatically enables/disables set paste, so you shouldn't have that in your .vimrc.

@ryanpcmcquen As of now I can confirm that the code still can't work on my tmux. Not even set noautoindent etc that OP suggests helps. Works perfectly out of tmux though.

Tmux 2.9a
VIM 8.1

@hafizhmakmur, so is it a tmux bug?

I'm seeing the same behavior as reported by @t-ye in the original description with GNU Screen:

Screen version 4.00.03 (FAU) 23-Oct-06

No problem with the same vimrc file outside of screen (using Putty). Setting the 3 no indent settings has NO impact for me (i.e. consistently bracketed paste mode is not doing a no paste).

[ryanpcmcquen]

I was never able to reproduce this issue, but would accept a PR that fixes it.

My comment ConradIrwin/vim-bracketed-paste#31 (comment) here shows something that works for me, its similar but different:

• t_SI / t_EI versus t_ti /t_te - https://vimdoc.sourceforge.net/htmldoc/term.html#t_SI

It's not the same but works for me with:

• Putty

• Vim 7.x and 8.x

• GNU Screen 4.00.03 and 4.05.00

    execute "set <f29>=\<Esc>[201~"

    imap <expr> <f28> XTermPasteBegin("")
    vmap <expr> <f28> XTermPasteBegin("c")
    cmap <f28> <nop>
    cmap <f29> <nop>
  

I'm not sure this is worth me posting a PR as its sufficiently different from this implementation (which is super nice and small) and I've not tested with tmux, I've only tested raw Putty and Putty+GNU-Screen - I also don't 100% understand the escape sequences

Thanks for making this available!
