Description

Is it possible to add a way to make MiniFiles.synchronize keep the changes to buffers if the query was refused and to know if it was refused or not?

I want it to allow me to rewrite 'l' map on file to synchronize, then open the file if changes to the file system were accepted.

Thanks for the suggestion!

I guess adding the third option of something like "No, (K)eep edits" might be a good idea. And making synchronize() return true if sync was done and false (with or without keeping edits) otherwise. I'll take a look.
