SVN commit 816498 by asimha:

Make the find dialog more usable, by making it interpret Messier / NGC
/ IC catalog numbers more intelligently.

"M93" is now automatically interpreted as "M 93" if the user typed it
in (and not if he selected some other object whose name contains M93
from the list) and so on.

Thanks to my friend Prasanna for pointing out this usability issue.
