[[!tag plugins/meta patch]]
I'd like to define [[plugins/meta]] values to apply across all pages
site-wide unless the pages define their own: default values for meta
definitions essentially.
Here's a patch to achieve this (also in the "defaultmeta" branch of
my github ikiwiki fork):

a quote in the text by writing `"` and so on.
