Strip extent information when passing text to external programs, select.el lisp/ChangeLog addition: 2011-09-21 Aidan Kehoe <kehoea@parhasard.net> * select.el (select-convert-to-text): * select.el (select-convert-to-utf-8-text): Ignore extent information in these functions, other programs can't do anything useful with it, and it actively interferes when copying from an ERC buffer to external programs-- #'encode-coding-string complains that the string is read-only, which is arguably in itself a separate problem, since it allocates a new string there's no reason for it ever to throw that error.
