Sure, that's a small speedup. Will do.

I wouldn't like to do this, for two reasons:

  * The output of "gpg --version" contains other stuff, that may change
    without notice. I can't predict which substrings this stuff may contain,
    five years from now.

  * The HP-UX shell behaves weirdly if the expansion of the 'case' argument
    is longer than ca. 100 or 128 characters. Saw this once, years ago, and
    since then I always made sure to use only small strings in 'case'.
    So, I cannot tell whether the problem is still visible (on HP-UX or
    on other deficient systems that may use a similar version of sh).
