Oh. I naively thought that the byte-compiler was providing positional
hints to f-f-s-for-symbol, but it's just a text search:

from find-function-search-for-symbol:

  ;; `regexp' matches definitions using known forms like
  ;; `defun', or `defvar'.  But some functions/variables
  ;; are defined using special macros (or functions), so
  ;; if `regexp' can't find the definition, we look for
  ;; something of the form "(SOMETHING <symbol> ...)".
  ;; This fails to distinguish function definitions from
  ;; variable declarations (or even uses thereof), but is
  ;; a good pragmatic fallback.

(Had me fooled until now, so I guess it's not so bad)

João, wondering where in bytecomp.el this could be hooked up...
