I have to admit that it took me a bit to understand what the "by" meant,
but I think it intends to convey:

  "sniff the symbol's language from the symbol's mangled name".

So s/by symbol/from symbol/ would be better, IMHO.

symbol_find_demangled_name says:

/* (...) attempt to find any demangling algorithm that works and
   then set the language appropriately.  The returned name is allocated
   by the demangler and should be xfree'd.  */

So IMHO, something like "la_sniff_from_mangled_name" would be
even clearer.

BTW, what do we do with the resulting demangled name?  Is
there some sort of guideline for options to pass to the demangler?
Some sort of output that we're aiming for?
