parentt7810: add test for grep -W and trailing empty context lines (diff)
downloadtgif-4aa2c4753d152aef810eaf3f3f4fa1df7035d9b0.tar.xz
grep: -W: don't extend context to trailing empty lines
Empty lines between functions are shown by grep -W, as it considers them to be part of the function preceding them. They are not interesting in most languages. The previous patches stopped showing them for diff -W. Stop showing empty lines trailing a function with grep -W. Grep scans the lines of a buffer from top to bottom and prints matching lines immediately. Thus we need to peek ahead in order to determine if an empty line is part of a function body and worth showing or not. Remember how far ahead we peeked in order to avoid having to do so repeatedly when handling multiple consecutive empty lines.
