Change subject: Updated builder-corrected-tag fixup to add placeholders always.
......................................................................
Updated builder-corrected-tag fixup to add placeholders always.
* echo "|foo" would parse to an empty string because this would
parse to a tr-token which the builder strips but leaves behind
a mw:StartTag meta-marker. findBuilderCorrectedTags function
wasn't properly processing these markers and possibly other
markers as well.
* Fixed addPlaceholderMeta helper function to be smarter and fix
this up. With this patch, this wikitext snippet now parses and
RTs correctly. There are notes in the file about possible
improvements which makes this text editable (currently VE will
likely ignore content wrapped in mw:Placeholder metas).
* 2 more wt2wt tests now green.
* Improves RT-ing of en:Drum tabs.

leading spaces

+ *
+ * A possibly fix for this is to wrap this in a span
with a public
+ * attribute that tells WTS that this doesn't need
escaping which
+ * would have to be cleared by VE if that text gets
edited.
+ *
+ * Another fix would be for nowiki escaping to get
smarter.
+ *
+ * But for now, leaving this note in place and using
placeholders.
