For historical reasons, `M-s o' provides the previous history element as
the default.  I had no intention to change this default (because I recall
there were objections to changing the default behavior).  So if you want
`M-s o' to provide a symbol at point, you can customize
`read-regexp-defaults-function' to `find-tag-default-as-symbol-regexp'.
