Parse multiple arguments in a row

[ston1x]

Background

Currently available arguments for clerk are: -f, -d and others. It is currently impossible to use two or more arguments in a row, e.g. git_clerk clerk -fd. The parser only understands them separately: git_clerk clerk -f -d

To do

• Allow any combinations of supported arguments, e.g. -fd, -df (it becomes more interesting when there are more than 3 of them. Just reversing them wouldn't help)
