Enhancement request

[Dave Yost]

The changecom macro is not enough.  To parse C, we need 2 kinds of comments.. 
/* */ amnd //.  Actually, if anyone does work on this, it would be good to be 
able to define nesting comments as well.

I think it would be useful if you extended changecom to be

  changecom(opt start1, opt end1, opt isNesting, ...)

where additional arguments are of the form: start2, end2, nesting2, and so 
forth.

Other implementations are possible, such as introducing addcomment(start, end, 
nesting) and removecomment(start, end), but these may possibly break existing 
scripts.

Thanks

Dave
