find-function-search-for-symbol in find-func.el is called for its

return value and not for side-effects but presently it moves point

around in the buffers it affects.  It needs some save-excursion

protection.  This is true for the most recent 25.1 release I looked at

and I don't think any changes have been made to it since then.

One example of where this causes a problem is in xref-location-marker

of elisp-mode.el.  Again, that is called simply to return the marker

but because it calls find-function-search-for-symbol, it can move

point and cause other problems.

It would be best if someone familiar with this first function made the

change to ensure it is correct.
