Wow, I just tested myself and you're right, line continuation within strings
DOES seem to work. I thought I found this to not work a long time ago. But,
it looks like this worked way back in 6.2.18, so I have no idea where I got
this idea. Sorry about that!

:help :map-<expr> has a few. Here's another:

:nnore <expr> h repeat("\<Left>", 5)

Your mapping should look like:

:nnore <expr> ,gg ':'.MyGit("new post")

Then your command can look something like:

:command! MyGit exec MyGit(<q-args>)

Your function must do nothing, but return the string you want Vim to put on
the command line, complete with <Left> characters. I'm not sure whether you
need to escape them like "\<Left>" or not, :help :map-<expr> should help
with that.
