 --NOTES
 --         See talk-page: [[Template_talk:Strlen_quick]].
 --
 --    [ These comments are skipped by &lt;noinclude&gt; so they will
 --      be omitted &amp; not sent in a formatted Internet page. ]
 --
 -- NOTE A1: This template counts the length of string {1} by
 --      comparing with the string truncated to 'n' long in a
 --      #switch for each set of lengths of {padleft:|n|{1} }.
 --      The first match will exit the #switch with the length
 --      number and exit the nested end-ifs. Max length is 70.
 --
 -- NOTE N2: This template was designed to use minimal levels
 --      as 5, to avoid the &quot;expansion depth limit&quot; when used
 --      in very large templates. By comparison, {str_len} was
 --      using over 9-13 levels of 40 total, during 2009-2011.
 --
 -- NOTE P3: To speed the results, the check for length is based
 --      on probability of an average length of 17/18, as found
 --      in Wikipedia titles, where length 5 is as rare as 31
 --      or longer. The average search is 6.5 uses of {padleft}
 --      but the weighted average for actual titles is near 4.
 --      When most strings are &gt; 49, then use {str_len}.
 --
 -- NOTE S4: This template CANNOT be subst-substituted by using
 --      {{subst:strlen_short|...}} to save only the results, or
 --      {{{{{|safesubst:}}}strlen_short}} using blank parameter.

 --HISTORY:
 --30Jan2011 Created to get length quickly in few nest levels.
 --31Jan2011 Removed spurious newline before &lt;noinclude&gt;.
 --31Jan2011 Set to return {{{extra|-1}}} when &gt; 70.
