It is high time to make the Admin directory an Isabelle component, see 
0bc8d90d2717, and to gradually raise the quality standards of the scripts 
there towards that of the Isabelle distribution in general.

I've already added "isabelle update_keywords" in 0bc8d90d2717, although it 
still lacks a proper "usage" for illegal command line, even just the 
conventional '-?' as error that leads to usage display.)

Note that I've now used the "_" to separate words in conformance to other 
Isabelle tools, like tptp_sledgehammer.  This is also more portable, 
because the "-" cannot be passed through nested /bin/sh as shell function 
(which is the reason why isabelle-process still has some snags in exotic 
situations).
