Newline through parser functions

See bugzilla:12974.

Examples of the problem

Semicolon

The tuples include A1, A2; B1, B2{{#if:IncludeC|; C1, C2}}.

gives

The tuples include A1, A2; B1, B2 C1, C2.

See also Newline in style.

Colon

Look{{#if:Detail|: bird}}!

gives

Look bird!

Hashmark

He said this is dumb.<sup>{{#if: UseHashmark|#|*}}</sup>

gives

He said this is dumb.

Asterisk

He said this is dumb.<sup>{{#if: UseAsterisk|*|#}}</sup>

gives

He said this is dumb.

…and tables

But those are the least of the problem, because you don’t encounter {| elsewhere too often.

Workaround

The tuples include A1, A2; B1, B2{{#if:IncludeC|<nowiki/>; C1, C2}}.

gives

The tuples include A1, A2; B1, B2; C1, C2.

The tuples include A1, A2; B1, B2{{#if:IncludeC|&#59; C1, C2}}.

gives

The tuples include A1, A2; B1, B2; C1, C2.

Look{{#if:Detail|: bird}}!

gives

Look: bird!

He said this is dumb.<sup>{{#if: UseHashmark|&#35;|&#42;}}</sup>

gives

He said this is dumb.#

He said this is dumb.<sup>{{#if: UseAsterisk|&#42;|&#35;}}</sup>

gives

He said this is dumb.*

Workaround failure

Workarounds are not possible for things like {{PAGENAME}} on a page like *foo.
