Yes it is a good solution. Better yet, you may want to put only your
modifications in a separate file and source that file instead of
directly changing tcl scripts in ns. That way you always have an original
reference.

I'm not sure what caused this, one possibility is that one single long tcl
line was somehow broken into two lines, or just syntax error. 

Since tcl is interpretted, this won't be captured during compilation.
