The `^L' appeared in built-in help.

[Hongyi Zhao]

I noticed so many `^L' appeared in Emacs' built-in help. According to
the ascii document shown below, this should mean '\f' (form feed):

$ man ascii | grep ' L$'
       014   12    0C    FF  '\f' (form feed)        114   76    4C    L

But I also noticed that this control character is not used evenly
throughout the document.

Any hints for this phenomenon?
