This is an arbitrary limit compiled into the editcap program:

Line 109 of editcap.c:

  static struct select_item selectfrm[100];

How many arguments do you need to pass to editcap?  We could look into 
changing this limit or removing it entirely to make it dynamically 
allocate space for as many arguments as fit on the command-line.
