Obfuscate the regexps to strip off the IBM compiler's copyright banners. I don't want bots scanning github to think they're real copyright notices because that could cause real problems.

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	44 Most of the changes in AnaGram 2.40 are under the hood - cleanup of

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	76 supported and available to the public. There is at present no GUI for
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	77 the Unix version. The long-term goal is to migrate the AnaGram GUI
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	78 away from the closed (and orphaned) IBM Visual Age class library to
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	79 something else, probably GTK, so as to support both Windows and Unix.
