Not exactly: going by the option's description in the manual, it follows 
symlinks for all arguments passed from the command line, but won't do 
that for any of the directories inside the searched directory that are 
also symlinks.

I don't think there's any visible change in behavior because of that 
change. It mostly mirrored the one in 2e55201b8085 for better/uniform 
approach to the problem.

The latter change fixed ignore entries not being applied by the default 
implementation of project-files with certain old versions of 'find'.

rgrep, which also has some ignores to handle, uses "." as the DIR 
argument, so it should see no change.

xref-matches-in-directory has no known callers anymore, but any 
third-party code should see the IGNORES honored better with those old 
versions of 'find'.

semantic/symref/grep.el doesn't use the "exclusions" argument.

And as for following the symlinks, the existing users of 
grep-find-template, which were changed, previously used a different 
approach: having DIR end with '/' (hence the file-name-as-directory 
calls which were replaced with directory-file-name calls).
