git pr can not deal with shell variable expansion correctly about git-repo-go

[jiangxin]

I am sure that the whole one line title can be sent to git using push-options, see test case:

• https://github.com/alibaba/git-repo-go/blob/master/test/t0400-upload-basic.sh#L277

Please check the code of "proc-receive" hook. May be only part of the title is sent to merge-request API.

It's wrong to add backslash before double quote characters. Please use --title "..." instead of --tiltle \"...\".

after some tests, I finally get it work. My script use expect programe to spawn a process

the code below does not work as expected

/usr/bin/expect <<-EOF
	set time 10
	spawn git pr --no-edit --reviewers $REVER --title "$DESC"
	expect {
	"*(y/N)?" { send "y\r"; exp_continue }
	"*did you forget to amend?)" { send "y\r" }
	}

use curly brackets ({}) to make the content inside {} passed as a whole

/usr/bin/expect <<-EOF
	set time 10
	spawn git pr --no-edit --reviewers $REVER --title {$DESC}
	expect {
	"*(y/N)?" { send "y\r"; exp_continue }
	"*did you forget to amend?)" { send "y\r" }
	}
