[teqc] teqc removal of SPLICE COMMENT

While it's true that `grep -v COMMENT DRAZEN.05O` will remove all lines
that have COMMENT in them, this will not necessarily produce a correctly
formatted RINEX file, and in particular it will _not_ produce a correctly
formatted RINEX file in this case.  (A RINEX file is a highly formatted
file!)  If the postheader lines have been minimized in number with
`teqc -phc ....`, then the splice points have two lines that (should)
look like:

                             4  1
RINEX FILE SPLICE                                           COMMENT

Better to do:

grep -v "RINEX FILE SPLICE" DRAZEN.05O | grep -v "^                            4  1" > newfile

Make sure you have the correct number of spaces!  Note that this approach isn't
true for any arbitrary RINEX file, but probably will create correct RINEX
in this case.

cheers,
