I'm not sure what you're wanting here.  You want the colons to
be able to have spaces between them?  Then the pattern becomes

  $PageTextVarPatterns['var::'] = 
    '/^([-a-zA-Z_ ]+)\\s*:\\s*:[ \\t]?(.*)$/m';

PmWiki's {$var} markup doesn't recognize spaces or hyphens
in variable names...  so in order for that to work we'd also 
have to redefine the {$var} markup.

  $PageTextVarPatterns['var::'] = 
    '/^\\s*([-a-zA-Z_ ]+)\\s*:\\s*:[ \\t]?(.*)$/m';

  # {$var} substitutions
  Markup('{$var}', '>$[phrase]',
    '/\\{(\\*|!?[-\\w.\\/\\x80-\\xff]*)(\\$:?\\w[-\\w ]*)\\}/e',
    "PRR(PVSE(PageVar(\$pagename, '$2', '$1')))");

I think this goes back to my first item of adding the \s* between
the two colons.
