Consider the doc-string of the function `mark' in simple.el.  It
contains the single-quoted symbol name `mark-even-if-inactive'.  Moving
there and typing C-h S RET will get you - if I recall correctly -
something like

"Not documented as a symbol: `mark-even-if-inactive"

`info-lookup-symbol' strips the trailing quote but does not strip the
leading backquote which is inconvenient.

Have `custom-unlispify-tag-names' non-nil (the default value), customize
`mark-even-if-inactive', move to the "Mark" in "Mark Even If Inactive",
and type C-h S RET.  Should get you something like

"Not documented as a symbol: Mark"

I don't use "unlispified" tag names, hence I normally don't care about
this.  However, I didn't want to write a patch without handling this
special (albeit standard) case.
