Subject: [PATCH] fix(scripts): gen_terminfo clears Windows terminfo
 definitions #36736

Problem:
`gen_terminfo.lua` clears out Windows terminfo definitions:

    rm -r /tmp/nvim_terminfo
    nvim -ll src/gen/gen_terminfo.lua

`src/nvim/tui/terminfo_builtin.h`:

    static const TerminfoEntry vtpcon_terminfo = {
      .bce = false,
      .has_Tc_or_RGB = false,
      .Su = false,
      .max_colors = -1,
      .lines = -1,
      .columns = -1,
      .defs = {
        [kTerm_carriage_return] = NULL,
        [kTerm_change_scroll_region] = NULL,
        [kTerm_clear_screen] = NULL,
        [kTerm_clr_eol] = NULL,
        [kTerm_clr_eos] = NULL,
        [kTerm_cursor_address] = NULL,
        [kTerm_cursor_down] = NULL,
        [kTerm_cursor_invisible] = NULL,
        [kTerm_cursor_left] = NULL,
        [kTerm_cursor_home] = NULL,
        [kTerm_cursor_normal] = NULL,
        [kTerm_cursor_up] = NULL,
        [kTerm_cursor_right] = NULL,
        [kTerm_delete_line] = NULL,
        ...

Solution:
Generate the database in 2 steps, don't concatenate the sources.
