I tried to avoid changing the default regexpflag because of the docs.
warning as regards memory when used with large pieces of data.

The syntax that achieved my desired goal is a two-step:

set v to change "^\\r+" into "" in v with regexp
set v to change "\\r$" into "" in v with regexp

(the second line catching any stray trailing CRs). My thanks to
Timothy and Emmanuel for pointing me in very much the right direction.

Cheers!
