[Bill Guyton <guyton@xxxxxxxxxxx>]

Forgive me if someone has already suggested this and it got shot down.
I was hoping to add support to mergecap.c so that a user can specify
- as an output file and have the output go to stdout.

Example:

	mergecap -w - infile1 infile2 ...

CVS Patch is below.

Thanks!
Bill Guyton
