I tend to agree with this, though if people decide they want it, you
could almost certainly tighten up the regexp some to reduce the chance
of it masking things (eg: I assume a starting anchor ('^') would be
correct here, and you could almost certainly add the rest of the columns
which are included in the $Id$ format using appropriately-typed
wildcards, etc...).
