templater: avoid recursive evaluation of string literals completely

Changeset 3d8bfe2ecf6d (released with 2.8.1) fixed "recursively
evaluate string literals as templates" problem (issue4103) by
introducing "_evalifliteral()".

But some parts in template expressions below are still processed by
the combination of "compiletemplate()" and "runtemplate()", and may
cause same problem unexpectedly.

  - 'init' and 'hang' of 'fill(text, width, init, hang)'
  - 'expr' of 'sub(pat, repl, expr)'
  - 'label' of 'label(label, expr)'

This patch processes them by "_evalifliteral()" instead of the
combination of "compiletemplate()" and "runtemplate()" to avoid
recursive evaluation of string literals completely.
