Citation strings are composed of one or more elements. Nested
citations, being less complex (and less informative) than non-nested
citations, are composed of only a single element, the
citation delimiter. This string is user defined in the variable
sc-citation-delimiter and has a default value of
Nested citations will contain a single space between the last level
(oldest) citation and the original text. It is usually a good idea to
sc-citation-delimiter a single character.
Non-nested citations are composed of four elements, three of which are directly user definable. The elements are concatenated together, in this order:
sc-citation-leader, and has the default value of a string containing a single tab character.
sc-citation-separator, and has the default value of a string containing a single space character.
For example, suppose, you were using the default values for the above
variables, and supercite provided the attribution string `Jane'.
In this case, the composed, non-nested citation string used might be
something like `\tJane> ' (the `\t' represents a tab
character). This citation string will be inserted in front of every line
in the original message that is not already cited. Supercite uses the
regular expression in the variable
sc-cite-regexp to determine
whether a line is already cited or not. The default value for this
"\\s *[-a-zA-Z0-9_.]*>+\\s *"
Nemacs users may want to set
"\\s *\\([a-zA-Z0-9]\\|\\cc\\|\\cC\\|\\ch\\|\\cH\\|\\ck\\|\\cK\\)*\\s *>+"
