-Subject: [PATCH] display the pagetitle() in linkmaps
-
-without this patch, linkmaps display underscores and underscore escape
-sequences in the rendered output.
-
-this introduces a pageescape function, which invoces pagetitle() to get
-rid of underscore escapes and wraps the resulting utf8 string
-appropriately for inclusion in a dot file (using dot's html encoding
-because it can represent the '\"' dyad properly, and because it doesn't
-need special-casing of newlines).
