[bug-diffutils] bug#20250: diff by size

[Andreas]

Dear diff-team,

this is not a bug but an idea for a diff option in further versions:

Idea:
comparison of two files by size only.

why?
makes comparison extremely fast; often no need to compare file contents
to get a first hint whether there is a difference at all

example:
- uploading a folder with a bunch of files to a slow motion cloud;
comparing each file by contents is very time consuming (...slow motion
cloud)
- as a first hint to find out about a possible difference could be the
comparison of file size for each file uploaded with the local ones


Thanks in advance for integrating this option in future diff versions.

Great tool, great diff team!
