[[!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.

This doesn't support multiple-argument meta directives like
link=x rel=y, or meta directives with special side-effects like
updated.
The first could be solved (if you care) by a syntax like this:
meta_defaults => [
{ copyright => "© me" },
{ link => "about:blank", rel => "silly", },
]
The second could perhaps be solved by invoking meta::preprocess from within
scan (which might be a simplification anyway), although this is complicated
by the fact that some (but not all!) meta headers are idempotent.
