25.0.50; isearch and query-replace histories do not remember if we were looking for symbols |

Hi. It is possible to look for a symbol, and for this information to be
lost when repeating a search. For instance, say I have this buffer:
=======
a b c
ab bc
=======
1. I put the point on the first 'a'
2. M-s . (search for symbol at point). This find a symbol 'a', so the
'a' in 'ab' doesn't match
3. C-g (quit the search)
4. C-s C-s (repeat previous search). Here emacs remembers we looked for
'a', but not that it was a symbol, so it finds the 'a' in 'ab' even
though it should not
A similar sequence is possible with query-replace:
1. Point on 'a'
2. M-s .
3. C-M-%, 'asdf' to replace the symbol 'a' with 'asdf'
4. C-g (quit before replacing anything)
5. C-M-% (repeat last replacement. The symbol-ness of 'a' was forgotten)
The simplest way to fix this would probably be to treat these as regex
searches wrapped in \_<...\_>. The downside is that to access the
history we'd have to do C-M-s C-M-s instead of C-s C-s, but maybe that
is ok. Thoughts?
