[[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). the output will look much better (at least in my wikis) with the "[[bugs/pagetitle function does not respect meta titles]]" issue fixed. the patch is stored in [[the patch.pl]] as created by git-format-patch. (btw, what's the preferred way to send patches, apart from creating a git branch somewhere?)
