Update README.md

[rmie]

Using '' instead of "" defers evaluation of e. g. $(pwd) until the alias is used. Additionally, set uid:gid and provide passwd and group from host, runs git as the current user instead of root

[ozbillwang]

can you add as usage 3?

@ozbillwang PTAL

[ghost]

I am getting a

Cloning into 'repo-folder'...
No user exists for uid 131
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

when using this third usage as alias.
Any idea?

I guess you are asking because of:

No user exists for uid 131

The assumption here is that /etc/passwd contains an entry for your uid (131 in this case), which might not be if e.g. LDAP is used to provide user and groups.
