bug#305: 23.0.60; no help xref for file-name-completion-ignore-case

[Drew Adams]

help-make-xrefs does not create a link on the text
`file-name-completion-ignore-case'. It does so for other such
variables, including `completion-ignore-case'.
 
emacs -Q
 
Eval this in *scratch*:
 
(defun foo ()
  (with-current-buffer (help-buffer)
    (help-mode-setup)
    (insert "xxxxxxxxx\n\n")
    (insert "`completion-ignore-case', `file-name-completion-ignore-case'\n"))
  (help-make-xrefs (help-buffer)))
 
M-: (foo)
 
`completion-ignore-case' has a link;
`file-name-completion-ignore-case' does not.
 
This is because the call in help-make-xrefs to intern-soft with arg
"file-name-completion-ignore-case" returns nil.
