Hi,

Take any file, code or not, but let's say it is code...
Now select two or more lines. The mark should be at the beginning of a line
and the point at the beginning of a line two or more lines further down. If
you copy this region and paste it somewhere else you get what you want.

However let's suppose that your theme is highlighting the region and you
comment the region with M-x comment-line. You will have the line at the
point:
1.- not highlighted before M-x comment-line
2.- commented after M-x comment-line

This is something you get used after n-ty something years of use. However,
it is confusing the "newer generation" because it doesn't happen on other
"popular" editors. Could we consider a variable customise the behaviour and
allow the last line *not*  to be commented when the mark is at the start of
line?

Just a random thought after talking to novice users,
