ssh:// prefix is not removed from URLs passed to git CLI

[kornelski]

Bug in v0.17.0. Still in v0.20.3.

What is the current behavior?

URL in the format git+ssh://host_alias:path.git is given to git clone as ssh://host_alias:path.git. This is not compatible with npm, which clones host_alias:path.git (without the ssh:// prefix). This changes the meaning of the URL in git.

(By host_alias I mean a name given in Host setting in ~/.ssh/config. I'm using git URLs in such format, because it allows me to configure specific SSH deployment keys for private github repos.)

What is the expected behavior?

ssh:// prefix should be stripped from URLs given to git CLI.

Please mention your node.js, yarn and operating system version.

yarn v0.17.0-20161111.1922. Tested again in v0.20.3.

#513 says git+ssh support is fixed, but this particular case still doesn't work for me in today's nightly.
