-    [[help:smart-tabs-insinuate][smart-tabs-insinuate]] enables smart tabs for a particular language,
-    but also it will only be used when [[help:indent-tabs-mode][indent-tabs-mode]] is
-    non-nil. The following function wraps up setting
-    ~indent-tabs-mode~ and enabling smart tabs for the language into
-    one thing:
+    The package has this really annoying behaviour that it turns
+    itself off if [[help:indent-tabs-mode][indent-tabs-mode]] is nil, even when you just
+    explicitly turned it on. The solution on the Emacs wiki is to set
+    indent-tabs-mode to t in a =c-mode-common= hook, which is a bit of
+    a hack, but I tried my own approach and it didn't work for no
+    apparent reason so I'm just going to do as I'm told.
