[patch] Fix indentation bug of Preprocessor directive continuation line

[h_east]

Hi Bram and list,

How to reproduce:
- Run vanilla Vim with 'cindent'.
$ vim -Nu NONE +"set cindent"
- Input bellow.
i#if aaa\<CR>bbb\<CR>ccc<ESC>

Expect behavior:
#if aaa\
bbb\
ccc

Actual behavior:
#if aaa\
bbb\
ccc


After the third line is not indent well.
NOTE:
This behavior occurs only outside of the curly bracket.

I wrote a patch contains test.
Sorry, it is still the old style test. I'll challenge it in this spring👍

Check it out.

NOTE 2:
This issue was reported by Ken Takata.

This test might be easier as an old style test.
