Repeat {expr} {count} times and return the concatenated result. Example:

:let separator = repeat('-', 80)

When {count} is zero or negative the result is empty. When {expr} is a List or a Blob the result is {expr} concatenated {count} times. Example:

:let longlist = repeat(['a', 'b'], 3)

Results in ['a', 'b', 'a', 'b', 'a', 'b'].

Can also be used as a method:

mylist->repeat(count)
