Custom commands must start with an uppercase character.
Examples
command! MyCommand call SomeFunction()

The ref keyword for callers of methods is now optional when calling into methods supplied by COM interfaces. Given a COM method with the signature
void Increment(ref int x);
the invocation can now be written as either
Increment(0); // no need for "ref" or a place holder variable any m...
A branch is just a pointer to a commit, so you can freely move it around. To make it so that the branch is referring to the commit aabbcc, issue the command
git reset --hard aabbcc
Please note that this will overwrite your branch's current commit, and as so, its entire history. You might loose s...

}
And the Comparator<T> interface requires one method:
public interface Comparator<T> {
public int compare(T t1, T t2);
}
These two met...
