Ok:
the outer (.....)+ is two things: a grouping "()" and "one or more"
(the "+");
BTW this is unneeded guys since this is purely for recognising
quoted lines, not matching the entire quoted marker
the stuff inside the outer () is:
[ \t]* zero or more "*" spaces-or-tabs "[ \t]"
then
([>|:}#%]|[A-Z]{2,3}>)
which is an alternation "(...|...|...)" meaning match one of the "..."
parts,
containing two alternatives:
[>|:}#%] one of the characters > | : } # %
or
[A-Z]{2,3}> exactly 2 or 3 "{2,3}"
of the characters in the range A-Z,
immediately followed by the character >
So in short it's looking for some leading whitespace and then either a single
quote marker ( "> | : } # %" ) or an attribution marker like "CS>" for lines
from "Cameron Simpson".
The outer "(...)+" is superfluous in my opinion.
