Hmm, right. The rest of the docstring talks only about errors though.
Should we change the whole thing? While technically more accurate,
saying "Regain control when a signal is signaled" sounds a bit funny.
Otherwise, fixing just that sentence:

 A handler is applicable to an error if CONDITION-NAME is one of the
-error's condition names.  A CONDITION-NAME of t applies to any error
-symbol.  If an error happens, the first applicable handler is run.
+error's condition names.  A CONDITION-NAME of t applies to any condition
+name.  If an error happens, the first applicable handler is run.

That, and possible silly code which does something like:

   (signal 'not-an-error-symbol "oops")
