bug#23415: sed bug with the D command verb

[Dylan Wagstaff]

Hi again,

I wanted to thank Davide Brini for providing such a nice answer to what
amounted to a complete brain fade on my behalf. The documentation I linked
to spells out very plainly that this is the case, but it was so late at
night (when one should sleep on it rather than submit bug reports) that I
somehow overlooked the fact no matter how many times I read it, and managed
to confuse it to be a similar relationship between the likes of p and P,
where a cycle completes afterwards.

Even with this glaring foolishness, Davide took the time to graciously step
through the execution cycle to leave no doubt as to what was happening
behind the scenes, providing a well rounded and extremely helpful answer
(which I shall never forget again!) rather than simply stating facts and
calling it done. I shall certainly also 'sleep on it' before submitting bug
reports in the future!

tl;dr: Sorry for wasting everyone's time, I feel ashamed. Thanks for
excellent responses.

Thank you,
Dylan
