bug#6439: `bkqt` <- eval-last-sexp return value => bkqt

[MON KEY <monkey@sandpframing.com>]

With point after the following:

 `bkqt`

`eval-last-sexp' returns => bkqt

e.g.

(progn
  (insert "`bkqt`")
  (apply 'eval-last-sexp '(nil)))

Likewise, there is this weird behavior:

(progn
  (insert
   "\n\(progn\n"
   "  \(insert \"`bkqt`\"\)\n"
   "  \(apply 'eval-last-sexp '\(nil\)\)\)\n`\n")
  (apply 'eval-last-sexp '(nil)))

Why does evaluating the grave char evaluate the sexp preceding it but also does
something like this:

 (with-temp-buffer (insert "`````") (apply 'eval-last-sexp '(nil)))

Which signals an EOF?

Whereas this something like this doesn't:

 (with-temp-buffer (insert "`,(quote nil)`````") (apply 'eval-last-sexp '(nil)))
