I believe Keep() is exactly what I want. Would you mind helping me
figure out how to use it? Markup() takes four arguments; I'm not sure
what the first two are for, but I gather the last to, $pat and $rep,
are the pattern and the thing that replaces the pattern.
Keep(), on the other hand, takes two arguments, which I cannot figure
out how to use.
So I have two questions: how do I structure a call to Keep(), and how
does Keep() fit into the larger picture? The Markup() call quoted
above does just about everything I want: the pattern is replaced by
the result of the function call to view_blog_digest() (which itself
relies on the captures from the regular expression defined as $pat).
Can I put Keep() before that? I'm not sure what the "<:block>" thing
is all about.
