_getconf

[Peter Stephenson <pws@xxxxxxx>]

_getconf has been written on the basis that all the variables are listed
inline and presumably the list can be kept up to date.  Wow, is my
outlook on life different from that.

Here's a modified version which I don't think loses anything but fixes
the implausible assumption.  (It appears it was only missing 261
variables on my system, however.)
