I agree there's an issue here; but I'm not sure help -e can really help here :s

What about:
hg help extensions <ext-name>
?
I also noticed that "hg help ext" is not resolving to "extensions".
Any reason for this? It might be interesting to match ^ext*, so the
command can be the shorter hg help ext <ext-name>

My first idea here was in my opinion weaker: "hg help ext<ext-name>",
"ext" standing as a suffix for extensions.


Whatever option we pick, I'd like "hg help extensions" to explain how
to access extension help: it looks like a common usage pattern to me
(first look at generic extensions help, then find more about a
specific extension)
