[Message part 1 (text/plain, inline)]

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
