As one user, I do sometimes search *Help* buffers.
Consider `C-h m', with multiple minor modes on.
`C-s' is a quick way to get around (as is `TAB').

No improvement, IMO.  No tidier, no more readable.
But different people have different preferences.

Don't get me wrong.  In some cases it can be useful
to replace the use of some envelope with just
highlighting (in some way) the enveloped text.

I do that with emphasized text in Info, for example.
That is, text such as _foo bar_.  But that choice is
controlled by an option, `Info-fontify-emphasis-flag'.

(All such things need to be optional, IMO.)

In some cases (e.g. "...") it generally makes sense
to highlight also the envelope char.  In other cases
(e.g. ‘...’, `...', <...>, '...'), it makes sense to
not highlight it (i.e., highlight only the text that's
enveloped).
