Feature request: "n or less" wildcard support

[paxperscientiam]

Some applications namespace configuration paths by version.

For example, Gimp does this:
Gimp 2.8 -- ~/Library/Application Support/GIMP/2.8
Gimp 2.10 -- ~/Library/Application Support/GIMP/2.10

etc

EDIT: fixed unintended strikethrough

Yes, Mackup only support contant paths right now, but we could imagine a parsing engine with simple variables in the paths like support for 1 ? or multiple * characters.

Wildcards would be very useful, could you add them?
