AnaGram interim repo (temporary): oldclasslib/include/charsink.h annotate

annotate oldclasslib/include/charsink.h @ 24:a4899cdfc2d6 default tip

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.
