Doesn't preserve outer spacing

See how it doesn't preserve outer spaces around " two inner spaces ". Is that the way we want it to behave? Or is it just the MediaWiki software?

All templates do that. Whitespace at the start and end is stripped in all named and explicitly numbered parameters, but not in unnamed ones:

• "{{echo| abc }}" → "@Abc:"
• "{{echo|1= abc }}" → "@Abc:"
• "{{#invoke:DemoTemplate|echo| abc }}" → "{{echo| abc }} → @Abc:"
• "{{#invoke:DemoTemplate|echo|1= abc }}" → "{{echo|abc}} → @Abc:"

Since whitespace is stripped before a parameter is passed into a module/template, nothing can be done within this module, but whitespace can be kept by adding <nowiki/> when using it:

• "{{echo|1=<nowiki/> abc <nowiki/>}}" → ""
• "{{#invoke:DemoTemplate|echo|1=<nowiki/> abc <nowiki/>}}" → "{{echo|'"`UNIQ--nowiki-0000000A-QINU`"' abc '"`UNIQ--nowiki-0000000B-QINU`"'}} → "

Doesn't preserve order of parameters

{{#invoke:DemoTemplate|Val|11|p=$|upl=acre}} → {{Val|11|upl=acre|p=$}} → $11/acre — CpiralCpiral 23:16, 19 July 2015 (UTC)
