Uh, because underscore is not a _word_ constituent character?
Still, locate-word-at-point could be changed to use \sw instead
of [-a-zA-Z0-9.]

Neither is [.].

Indeed, nor is [-].

Possibly the expression could be customized by the user or the active
region could be passed as the search-string.
You could try:

(require 'locate)
(defalias 'locate-word-at-point 'word-at-point)
(autoload 'word-at-point "thingatpt")


(require 'locate)
(defalias 'locate-word-at-point
          (lambda () (symbol-name symbol-at-point)))

Of course I can do that. But if "_" is a proper character in filenames
then why not change the default.

I guess I took "word" in the name of the function too literally.  But if
you want to match any valid file name character, it's simpler to exclude
the few invalid characters (NULL, slash, perhaps colon, etc. depending
on the platform).
