[BZ#777675] Make reduction of comparison criteria to size and timestamp a comparison option instead of an application option
Submitted by Kalle Richter
Link to original bug (#777675)
Description
The option to limit the comparison to the file size and the modification timestamp should be set at every comparison because
- one might forget that it has been set and misinterpret the comparison result
- one might want to run comparisons in parallel (since meld allow that) and use content comparison for the one and size/timestamp comparison for the other
The initial value might be configurable (e.g. always content-based, always size/timestamp or remember last) or not.
