bug#37458: 27.0.50; number-at-point misses hex

[Andreas Röhler]

number-at-point from thingatpt.el doesn't recognize hex-numbers.

Currently defined like that:

(defun number-at-point ()
  "Return the number at point, or nil if none is found."
  (when (thing-at-point-looking-at "-?[0-9]+\\.?[0-9]*" 500)
    (string-to-number
     (buffer-substring (match-beginning 0) (match-end 0)))))

Maybe make the regexp customizable?

Thanks,

Andreas
