Sigh.  Of course right after the 1.10.2 release it dawns to me what the
problem was in this case.  Sorry about that.

Please try this patch.  Thanks.  OK to put you in THANKS?
(I still need to write a test case for this.)

Cheers,
Ralf

    Let `missing' also work with versioned and prefixed programs.
    
    * lib/missing: Ignore prefixes of `gnu-', `gnu', and `g' when
    testing for known programs; also, ignore suffixes.
    * NEWS, THANKS: Update.
    Report by Tim Rice.
