General point about comfort noted, but they don't do the same thing.
$^path(N) is an equivalent to your perl expression. The snippet throwaway84846 posted also removes duplicates and collapses symlinks from /usr-merge for example.
If you run "apt source" for the package you'll see it - like lots of other packages - point you to the git repository when the packaging is maintained in a public git repository. The Vcs-Tag field in the package lists is the magic that triggers that message.
I wholeheartedly recommend How Parliament Works¹ for people who want a deep dive on these points. It is nowhere near as dry as you'd imagine for a five hundred page book about parliament.
While used copies are super cheap I'd also recommend picking up a current revision. Recent years have seen far more use(or attempts to use) some of the more obscure tools of both houses. The updates include more explanation of those topics, along with descriptions of recent cases before the courts.
dmr's reference manual¹ used it, see section 9.10.
Matt Dillon's DICE would have been popular on the Amiga then, and it looks like it also favored parens. The latest tarball of DICE² is pretty fun for a spelunking session, if you're feeling nostalgic. It makes for an interesting mix as it pulls in a few contemporaneous non-Dillon tools with varying styles.
Many people have given their "why," but I'll give another "how".
castget¹ is a simple tool that does exactly what you want, just add a feed URL and it pulls all the episodes. It has a nice catchup mode so you can add feeds that you've listened to elsewhere without pulling all the old episodes too. hpodder² is another tool I've used in the past, but I can't remember why I switched.
Depending on how much you like cobbling together your own solution html-xml-utils³ makes it incredibly easy to script a solution. For example, "curl feed | hxselect -c -s '\n' 'enclosure::attr(url)'" would list just the URLs. feedparser⁴ is a battle tested solution for processing feeds if you'd prefer a proper parsing solution over a hacky shell script(it will correctly handle different formats without any extra work for example).
The restore interface is really clean, I like it a lot. I'll admit I wasn't super interested when I first clicked(I was just checking to see how it compares to other tools), but the screencast sells the interface extremely well.
Full tip of the hat for the documentation in general; the intro and screencast are great, and the more thorough documentation below the fold is fantastic too!
Given that we're in a vim story, I'll reply with a little vim tip…
Vim has digraph support built-in¹, so for your example the first few digraphs are In, p*, >=, h*. It is also how I typed the ellipsis on the first line of this comment(,.), and the superscript footnotes(1S and 2S).
A more complete Unicode solution for vim is available in Christian Brabandt's excellent plugin².
I was thinking that number seemed crazy, as it is closer to ~10k at 3km for me(near Cambridge, UK). However, using that site and checking a few friends houses I see Cairo isn't that unusual; ~400k in Camden, 750k in Paris' 11th. And, making a couple of guesses at denser places led me to 1.7 million in Mumbai.
If anything it makes more amazed that regular wifi works as well it does between the house and garden, and I'll try to remember that next time I'm bemoaning its magic.
Assuming it’s mostly accurate (it has errors in my area), you can find bits of Cairo that exceed 2.1 million in a 3km circle, and Mumbai I can get over 1.8 million.
I’m in New Zealand and at that density you could fit our entire population in just over 2 of these 3Km circles.
I feel irritated when people stand too close to me, but at the Cairo density there must be tens of people within a stone throw.
