Well... Sometimes you just can't run a program you find (think of
cross-compiling). Sometimes the program doesn't understand --version,
and may just start reading from stdin (so that configure hangs
forever), or doing something totally unexpected.
And then, many times, it just won't do anything useful, and all you'll
get is a message telling the usage of the program, because it doesn't
understand --version.
I'd rather special-case --version so that we only do it when we know
it's a reasonable safe thing to do.
