[feat request] option to ignore/include files using rsync-filter syntax

[renatocoutinho]

The idea is to add the ability to pass "-F .rsync-filter" and have it ignore the files inside (using rsync's syntax). The rsync syntax could probably be rewritten as a big (set of) regex.

Reasoning: I often use dust prior to backing up messy directories with rsync, and exclude some files/dirs using rsync filters, then I re-run dust excluding all those files/dirs by hand - if dust had this feature, the process would be a lot easier.

rsync does something more complicated with only "-F" which is to recursively check for .rsync-filter in every sub-folder, that does look more complicated to implement.

  -I, --ignore-all-in-file <FILE>
          Exclude any file or directory with a regex matching that listed in this file, the file entries will be added to the ignore regexs provided by --invert_filter

Can you make this work with the existing above flag -I ?

-I is like -v only it will take a file which can contain multiple regex.

Or perhaps you want to use -v "\.rsync-filter - which will ignore files in the .rsync-filter directory.

No, the syntax is quite different. For instance, to exclude a folder foo in the top dir with rsync-filter I use

- /foo

and this is not recognized by dust. I could try and change this to just

foo

but now this excludes any files or folder that contain "foo" in the name, and something like

^foo$

doesn't work at all! (by the way, this doesn't work even with -v on the command line, I think this is probably a bug? Will re-read docs and search for issues before filling a new issue later)
