it looks this is not true , at least per my test:
let me ignore the "repeat" part of the issue for now:

//with this new code
function! MyGit(commitmsg)
let commitmsg=a:commitmsg
let GitCmd=":
\!git add -A .;
\git commit -m \" .
\commitmsg . \";" . "
\git push origin master"

echo GitCmd
endf
command! -nargs=? MyGit :call MyGit(<q-args>)
nn ,gg :call MyGit("new post:")<CR>


so If I test with echo in the code, I got:

:!git add -A .;git commit -m " .commitmsg . ";git push origin master
Press ENTER or type command to continue

so at least the line continuation for the "let var = " looks fine.

this I agree, so I fixed it with just one "!" in the head of the whole
string and use ";" to connect multiple external shell commands.

I understand,thanks!

this is how I changed my current code.

this part I don't understand...
I couldn't find a close example to my scenario ...

strangely that if I use "return GitCmd", I got just nothing...
since I already "return" the commands that I needed for the Ex command,
shouldn't I now get the whole bunch of the command strings waiting in
the vim command line?
