SSH config sometimes gets edited in a wrong way when running gogit set

[seppedelanghe]

Observation

When running gogit set multiple times, the wrong block in the ~/.ssh/config file gets edited sometimes, resulting in the same block twice. ~/.gitconfig and ~/gogit.ini seem like they get edited correctly

For example:

A config like:

Host github.com
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_a

Host github.com-b
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_b

Becomes:

Host github.com-b
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_a

Host github.com-b
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_b

Instead of:

Host github.com-a
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_a

Host github.com
    Hostname github.com
    User git
    Port 22
    IdentityFile ~/.ssh/id_rsa_b
