+[[ikiwiki/directive/linkmap]]s display the file name instead of the pagetitle, showing unsightly underscore escapes and underscores instead of blanks to users.
+
+the attached [[!taglink patch]] fixes this; from its commit message:
+
+ 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).
