Refactor all translation strings that have ambiguous placeholders.

E.g. "%link_startClick here%link_end" is now '<a href="%url">Click here</a>'.

Note: This isn't always the best solution. E.g. consider "Foo <a href='%url' class='gDialogLink'>bar</a>." Now the translator has to deal with 
preserving CSS classes too...
