bug#14390: 24.3.50; (wrong-type-argument stringp t) from `read-regexp'


From: Drew Adams
Subject: bug#14390: 24.3.50; (wrong-type-argument stringp t) from `read-regexp'

The backtrace is not from emacs -Q, but I think the same problem is there.
 
`read-regexp' binds SUGGESTIONS to this:
 
(append
  suggestions
  (list
   (find-tag-default-as-regexp) ; <======= SHOULD return a string
   (car regexp-search-ring)
   (regexp-quote (or (car search-ring) ""))
   (car (symbol-value query-replace-from-history-variable))))
 
The problem is (find-tag-default-as-regexp), which will return `t' when
TAG is nil.  `t' is not a valid suggestion: SUGGESTIONS must be a list
of strings.
