About this RE. "." matches anything, also newlines, so (.*\n)* is the
same as just .* (ignoring captures). But you probably do not want this,
so you should put (?n) in your RE (traditionally, at the start of it).
You also might want to quote the string with {} instead of "". Read
https://www.tcl.tk/man/tcl8.4/TclCmd/Tcl.htm for why (it is short; when
you have read it, you will know *all* Tcl syntax. Well maybe read re_syntax
as well).
