Whitespace is lost during copy-paste if it's at the end of the terminal line

[nh2]

What Operating System(s) are you seeing this problem on?

Linux X11

WezTerm version

20220101-133340-7edc5b5a

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

No, and I'll explain why below

Describe the bug

If I have a wrapped line like this (note, whitespace at the end of the first line, the string typed is aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa BBB):

niklas:~/ $ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa  
BBB

and I select it with the mouse, copy-pasting it into another wezterm instance with Shift+Ctrl+C, Shift+Ctrl+V, then the whitespace from the middle is lost:

niklas:~/ $ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaB
BB

The pasted string is now aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaBBB (2 spaces in the middle were removed).

To Reproduce

No response

Configuration

local wezterm = require 'wezterm';

return {
  -- Enable the scrollbar.
  -- It will occupy the right window padding space.
  -- If right padding is set to 0 then it will be increased
  -- to a single cell width
  enable_scroll_bar = true,

  scrollback_lines = 1000000,

  -- https://wezfurlong.org/wezterm/config/appearance.html#defining-your-own-colors
  colors = {
    -- The color of the scrollbar "thumb"; the portion that represents the current viewport
    scrollbar_thumb = "#aaa",
  },

  font = wezterm.font("JetBrains Mono"),
  font_size = 11.0,

  -- Disable ligatures in most fonts, see https://wezfurlong.org/wezterm/config/font-shaping.html
  harfbuzz_features = {"calt=0", "clig=0", "liga=0"},

  use_fancy_tab_bar = false, -- I like the terminal-font style for tabs better
  hide_tab_bar_if_only_one_tab = true,

  exit_behavior = "Close", -- like VTE terminals

}

Expected Behavior

Copy-pasting preserves input exactly.

Thanks for the report; this is fixed now in main and should show up in a nightly building within the next hour!
