Ow.  My eyes hurt from that.  How about we rewrite that as a native Perl
script:

    #!/usr/bin/perl
    $^I = ""; # this is -i
    while (<>) {
      s/\$(Id|Revision):.*?\$/\$$1: \$/;
      print;
    }

That's kinda surprising coming from the resident Perl guru.

I am so used to the command line "-i -p" that I did not even
know what $^I does, and I would have lost without your "# this
is -i" comment.  That alone makes the Uwe's one more readable
for me ;-).

May I suggest a compromise? : 

#!/usr/bin/perl -i -p
s/\$(Id|Revision):.*?\$/\$$1: \$/;
