Details:

PROBLEM:
On commands like
find sourcedirs  -sometests  -exec  cp '{}' destinationdir/ +
find complains
find: missing argument to `-exec'
because the placeholder '{}' must TERMINATE the command called by find.

FEATURE REQUEST:
Usability of find would be improved, if
(a)  above mentioned error message would be more instructive,
(b)  the currently redundant placeholder could be omitted or even better,
(c)  if the placeholder would be really functional and allow find usage like
my example above.

WORKAROUNDS are known but they lag the advantages of find operator '+':
use trailing \; instead of + or
use find ... -print0 | xargs -0 ...
