Description:
LibreOffice work with external links and relative path... But it's not obvious.

External link always displayed as absolute path. 
My file system:
./test.ods
./a1/result.csv
./a2/result.csv
./b1/result.csv
./b2/result.csv

I what to insert data of all result.csv, I expect link as file:///a1/result.csv or file:///./as.csv or a1/result.csv
But i see file:///some/my/path/a1/result.csv
Of course, if i move files from /some/my/path to /other/path i will see link as file:///other/path/a1/result.csv, but it's not obvious

Steps to Reproduce:
1. Enable at Tools - Options - Load/Save - General  "Save relative path to file" 
2. Select Sheet -> External Links
3. In form select any csv file
4. File always with absolute path. 
5. Push Okay

Try to edit absolute path to relative

1. Select Edit -> Links to External Files 
2. Try to change absolute path to relative (for example file:///./test.csv or file:///test.csv).. but it still absolute.

Actual Results:
relative path like as:
file:///a1/result.csv 
or
file://./a1/result.csv
or
a1/result.csv

Expected Results:
This will make the user experience with LibreOffice more intuitive.
