2.1 Citation Elements
=====================
“Citation strings” are composed of one or more elements. Non-nested
citations are composed of four elements, three of which are directly
user definable. The elements are concatenated together, in this order:
1. The “citation leader”. The citation leader is contained in the
variable ‘sc-citation-leader’, and has the default value of a
string containing four spaces.
2. The “attribution string”. This element is supplied automatically
by Supercite, based on your preferences and the original message’s
mail headers, though you may be asked to confirm Supercite’s
choice.

3. The “citation delimiter”. This string, contained in the variable
‘sc-citation-delimiter’ visually separates the citation from the
text of the line. This variable has a default value of ‘">"’ and
for best results, the string should consist of only a single
character.
4. The “citation separator”. The citation separator is contained in
the variable ‘sc-citation-separator’, and has the default value of
a string containing a single space.
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 ‘" Jane> "’. This citation string will be inserted in
front of every line in the original message that is not already cited.
Nested citations, being simpler than non-nested citations, are
composed of the same elements, sans the attribution string. Supercite
is smart enough to not put additional spaces between citation delimiters
for multi-level nested citations.
