bug#25591: 25.1; M-% offers to repeat last search, but forgets that it was a "symbol" search

I don't know if this is a bug, but it's disappointing and inconvenient.

Start emacs with -Q, and type into the *scratch* buffer these 10 characters:

    I ate this

Now do C-a to move point to the beginning of the line.

Now replace the symbol "i" with "u":

   M-s _ i M-% u RET !

So far, so good: we are looking at

   U at this

which is correct.

Now try to repeat the replacement:

   C-a M-% RET !

This changes the "i" in "this" to a u, even though that "i" isn't an
independent symbol.  I was hoping that it would do nothing.
