- % xstring_funcs
-
- String editing functions.
- Supports insert mode (with big cursor).
- The field variable should be a char *.
-
- This is an "extended" version of string_funcs that accepts
- characters beyond the normal printable range (i.e. beyond
- character 127) This is useful for European character sets.
