Bug w/matching control

[Felix Rosencrantz <f_rosencrantz@xxxxxxxxx>]

I'm seeing a problem with matching control and characters being deleted. I'm
using the data from workers/13320

I've attached a patch to 54compmatch.  I think the output should be the same as
the previous testcase.  Though this time with input of "g-2", we get a
"glibc-", with the 2 deleted.  This isn't checked in, since it won't pass.

The actual output seen from the test is:
! line: {tst glibc}{-2.1.94-3.i386.rpm}
  COMPADD:{}
! INSERT_POSITIONS:{9:27}
--- 1,3 ----
! line: {tst glibc-}{}
  COMPADD:{}
! INSERT_POSITIONS:{10}
