* Avoid adding existing selections in `select_add_next`
* Use the first available selection as delimiter in `select_add_next`
* Fix returning searches with newlines in `search.find`
* Fix repeat search when the last result spanned multiple lines
Use regular expressions instead of Lua patterns for find and replace editor commands.
Syntax files can now use regex or Lua patterns as before keeping backward compatibility for plugins.
