[[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, and can
be pulled from the abovementioned branch.
