Hi Bram and list,
How to reproduce:
- Prepare the following script file
$ cat sample.vim
e aa.txt
augroup sample
autocmd!
autocmd BufNew * tabedit cc.txt
augroup END
normal! i1
tabedit bb.txt
- Run vanilla Vim with above script file
$ vim -Nu NONE -S sample.vim
Expected behavior (I think):
- Three tabpages is opened.
1st: aa.txt (modified)
2nd: bb.txt (not modified) <-- current tabpage
3rd: cc.txt (not modified)
Actual behavior:
- Three tabpages is opened.
1st: aa.txt (modified)
2nd: aa.txt (modified)
3rd: cc.txt (not modified) <-- current tabpage
I wrote a patch and test.
Check it please.
NOTE 1: This issue was reported by Norio Takagi.
NOTE 2: The following part of the patch is a change not related to the main
topic :-)
