git clone always give error message,fatal: ''mongodb'' does not appear to be a git repository, with a wired double quotes

$ git clone ssh://gitbk@192.168.2.100:mongodb
Cloning into 'mongodb'...
gitbk@192.168.2.100's password:
fatal: ''mongodb'' does not appear to be a git repository ---------------this is the wrong output of git-upload pack, git clone will call the git-upload-pack in remote server
fatal: Could not read from remote repository.

BUT I TRIED THIS ,IT WORKS

$ ssh gitbk@192.168.2.100 "git-upload-pack mongodb"
gitbk@192.168.2.100's password:
0000----------------this is a right ouput is git-upload-pack

I found instead of single quotes of ''mongodb''in err msg ---fatal: ''mongodb'' does not appear to be a git repository---, gives a wired double quotes, and I tried in local the 'git-upload-pack' command, it only give single quote in its err msg.

I think something wrong when transferring the repo path to ssh remote server, shoud be caused by the openssh

Reproduce the failure with the shown git clone command and compare it with the direct ssh git-upload-pack invocation. Trace how the remote repository path is transferred and quoted for the SSH command, then verify that git clone produces the same repository-path handling without doubled quotes.
