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.

Initialize remote repo with branches:

  $ hg init remote
  $ cd remote

  $ echo a > a
  $ hg ci -Ama
  adding a

  $ hg branch br
  marked working directory as branch br
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb

  $ echo c > c
  $ hg ci -Amc
  adding c

  $ hg log
