The Economist used a hyphen after an adverb ending in “ly”—did it err or am I missing something?

From Mr Bush’s first veto in the July 22, 2006 Economist (subscription required):

And a decision by Mr Bush in 2001 allows federally-funded scientists to experiment on the few dozen embryonic stem-cell “lines” that already existed then, which can be propagated in a laboratory [emphasis mine].

I don’t like pointing out grammatical mistakes unless I’m on the clock or they’re amusing (yes, I know that the capitalization of the tags on this site is inconsistent—it’s a software issue, however, and not a grammatical one). In fact, I try not to edit when I am reading for pleasure—it slows me down.

When The Economist breaks a convention, however, (and not just by using quirky British English) I run to my grammar books.

From the adverbs entry (p. 36) of The Economist Style Guide (remember when I wrote that this book was a good reference?):

Adverbs do not need to be linked to participles or adjectives by hyphens in simple constructions: The regiment was ill equipped for its task; The principle is well established; Though expensively educated, the journalist knew no grammar. But if the adverb is one of two words together being used adjectivally, a hyphen may be needed: The ill-equipped regiment was soon repulsed; All well-established principles should be periodically challenged. The hyphen is especially likely to be needed if the adverb is short and common, such as ill, little, much and well. Less-common adverbs, including all those that end -ly, are less likely to need hyphens: Never employ an expensively educated journalist [emphasis mine].

Did the impeccable Economist err or am I missing something?

I saw the writing on the bathroom wall that this job would be tough

I was at a client site for a meeting and saw this sign:

It’s not good when even the custodians are verbose. (And no, I’m not in the habit of taking pictures in bathrooms; I happened to have my cell phone with me, which has a camera.)

It reminded me of my job during high school at an electronics retailer: I told the warehouse supervisor that we could use more toasters. He responded that he’d take care of it as soon as he finished “procuring the end cap.” His name was Dante, however, so I figured maybe he was entitled to a little poetic license.

Nope, she definitely can’t do that

On the Olympics last night, the announcer at the women’s halfpipe competition referred to one of the athletes’ chances of winning a medal by saying, “She can definitely podium.”

This gaffe is just part of the trend of sports commentators pushing for brevity at the expense of, well, making sense. Throughout this past football season, NFL announcers would say that a player was “out with a hamstring.” Since when did having a hamstring preclude one from being able to play football?
