User:Jiangxin/Patch Indent Pre

Support raw html ouput from extension

Indent_PRE means before PRE block (<pre>), there are several colon and the rander page shows a indented PRE block. When using UseMod wiki, I like it's indent pre syntax, but MediaWiki seems not support it. This patch lets MediaWiki support a indent pre feature.

Indent_PRE 就是在 <pre> 之前有若干个表示缩进的 冒号。 UseMod wiki 支持这样的语法，但是 MediaWiki 1.5.2 并不支持。 下面这个 Patch 提供了 MediaWiki 缩进 pre 的语法。

Bug 1581: pre over multiple lines in lists (duplicate of 1518) describe this problem: pre block can not be used in list. Though I have fixed it with the following patch, I find out these is another solution, which can solve another MediaWiki annoyance. Bug 1115 described the another annoyance of the current implement(1.5.2) of list. The patch I wrote fixed both the bug/annoyance: User:Jiangxin/Patch Blankline As List Terminator

Bug 1581: pre over multiple lines in lists (duplicate of 1518) 详细描述了 Wiki 的这个问题：不能在列表中使用跨行的 PRE 语法。 虽然我已经用补丁: User:Jiangxin/Patch Indent Pre 修复了这个问题，但是我发现另外的一个解决方案，并且可以解决另外一个 MediaWiki 受限制的地方。 Bug 1115 描述了由于 list 以回车结束导致不能分行写的困扰， 并建议以遇到空行或者下一个 list 时终止当前 list。 我关于这两个 Bug 的解决方案，参见： User:Jiangxin/Patch Blankline As List Terminator
