[bug-diffutils] bug#63553: diff command: issue with -B option (--ignore-blank-lines)

[Alex Escodro]

Hello and good morning!

I'm a software developer improving my skills in linux shell programming, and while experimenting with diff I came across a situation where blank lines seem to not be ignored even though -B (or --ignore-blank-lines) option is used.

I am not sure if it is a bug or some aspect of diff's output technically referred to as "normal".

I posted a question to Stackoverflow containing detailed information to reproduce the issue:

Thanks, and best regards
