Suggesting {{nse:...}} since -e suffix is used to mark _e_ncoded.

I prefer {{ns:user_talk}} to be "User talk" (no underscore),
so {{nse:...}} is introduced for the case that underscore is really needed.

Another reason for this is that, the current behavior of {{ns:...}} is inconsistent with either {{NAMESPACE}} or {{NAMESPACEE}}.
Since,

• {{NAMESPACE}}: no underscore, no % encoded
• {{NAMESPACEE}}: has underscore, has % encoded

while,

• {{ns:...}}: has underscore, but no % encoded

so, theoretically, {{ns:...}} cannot be used in the either the context that {{NAMESPACE}} or {{NAMESPACEE}} can be used.
