[feature] Directory Comparison File Filter: match against relative path
Currently, it is not possible to have a filter entry that matches against a specific subdirectory tree, as the match/filtering is performed just against the directory entry
https://gitlab.gnome.org/GNOME/meld/blob/master/meld/dirdiff.py#L774-777
So, a filter like some/sub/dir/*
will never match
The relative path should be to the start folder of the directory comparison (like .gitignore)
