Perhaps TCL relies on the system regular expression library, and
Cygwin's does not support repetition operators? Anyway, the TCL
manual says they are supported, so I'm surprised by this. Maybe Chris
Faylor knows something about it.

I'd use variables.
set item "-?\[0-9\]+, "
set items "$item$item$item$item$item$item$item$item"
append items "$item$item$item$item$item$item$item-?\[0-9\]+"
and that's 16.
