Similarly to the use of a single `*` or double `**` asterisk, a pattern ending with a slash `/` denotes an arbitrary number of characters or folder names. Excludes have to be marked with a leading exclamation mark `!`. The order of filters is relevant; a later inclusion overrides an earlier exclusion, and vice versa.
