This assumes that command-line-args resolves symlinks in the Emacs
program's name?  Or that the 'comm' attribute in process-attributes
does NOT resolve symlinks?  Because otherwise the above will cause
false negatives.  And on Windows, there's the issue of the ".exe"
extension, which could be in one, but not the other, I think?
