Vorlage:Block bug documentation

If the block-formatted content begins with a list (or any other wikimarkup that is dependent upon a specific markup character being at the beginning of a line) then due to a bug in MediaWiki, a <nowiki /> must exist before the list (or whatever) starts. Compare:

	code	result
FAIL	{{Block bug documentation|1= *Firstly, ... *Secondly, ... *Thirdly, ... }}	Vorlage:Error
Works as intended	{{Block bug documentation|1=<nowiki /> *Firstly, ... *Secondly, ... *Thirdly, ... }}	Vorlage:Error

To embed a table in block markup like this, the block template's content parameter must be named or numbered and include the self-closing noinclude – as in |1=<nowiki /> – then every | character in the table markup must be escaped with {{!}}. An alternative is to use explicit HTML <table>, <tr>, <th>, and <td> markup.
