"Regexps" page in the Emacs v21 manual.  [Probably the corresponding page
in the elisp manual, too.]

In this page it says:

:`\''
:     matches the empty string, but only at the end of the buffer or
:     string being matched against.

I believe that something like the following should be appended:
"If narrowing is in effect, it matches at the end of the accessible
portion of the buffer."

I think it would also be helpful if it was mentioned (at least, in the
elisp manual) that reaching the limit in functions such as
(search-forward-regexp re limit) doesn't count as "at the end of the
string".

[Corresponding remarks also apply to the description of \`.]

(like "aa"), remove one of them (leaving, say, "a").
