feature/integration-of-dictionary-el 81ebe86 04/17: Show error message when asking to match for nothing

[Torsten Hilbrich]

branch: feature/integration-of-dictionary-el
commit 81ebe86d8deace5cc39979a42dcf062bdaa830c4
Author: Torsten Hilbrich <torsten.hilbrich@gmx.net>
Commit: Torsten Hilbrich <torsten.hilbrich@gmx.net>

    Show error message when asking to match for nothing
    
    * lisp/net/dictionary.el (dictionary-popup-matching-words): Show error
    if neither the parameter nor the word at point are defined
    
    This avoids an error later on when the nil value is used as string
    within dictionary-encode-charset.
