[pmwiki-users] TextFormatting: [+ big +] vs. '+ big +'

[Christian Bartolomaeus]

Hi,

I always used [+ +] and [- -] for bigger or smaller text. That's what
Site/EditQuickReference [actually it was the former
PmWiki/EditQuickReference] told me to do when I started using PmWiki
and I never thought about it anymore. 

Just today, after someone asked on pmwiki-users-de, I noticed that the
guiedit button for "small text" uses '-small text-' and the button for
"big text" uses '+big text+'. 

I took a look at scripts/stdmarkup.php and learned that the different
methods generate different HTML-Output:

  [-text-] -> <small>text</small>
  [+text+] -> <big>text</big>

  '-text-' -> <span style='font-size:80%'>text</span>  # or similar
  '+text+' -> <span style='font-size:120%'>text</span> # or similar

The ChangeLog says that '- -' and '+ +' were introduced with Version
2.0.devel11 in october 2004.

Now I took a look at the Documentation:

* EditQuickReference only mentions [- -] and [+ +]
* BasicEdition also mentions only [- -] and [+ +]
* MarkupMasterIndex mentions both methods but doesn't give further
  informations
* TextFormattingRules gives [- -] and [+ +] as the "main" method and
  mentions '- -' '+ +' as "other styling"

So my question is: Is there a recommendation which method to use? If
so, I would suggest to change the Documentation accordingly. (I can do
that next week.)

Thanks

Christian
