It'd be more normal to omit \ in a braced list though, so I think
the version without is more natural Tcl style.

The reason I avoided \ was because it's a "native" continuation marker
for C and C++, but not for Fortran, Ada and others. So using \ would
change the way the comment is treated by some front ends and not others.
E.g. things like:
// a \
// b
trigger:
warning: multi-line comment [-Wcomment]
(Maybe moot anyway given Mike's response.)
