Re: [bug-gawk] pretty-print eats header comments

[Aharon Robbins]

Hi.

Sorry for the delay in replying.

I've asked my team member who did this work to look at this.

In general, getting the comments right is a hard problem, since
comments don't really exist in the grammar.  We've done the best we
can, but it may not be solvable in a way that gets things completely
right every time.

Thanks,

Arnold
