The manual already states
| Don't rely on `\' being preserved just because it has no special
| meaning together with the next symbol. In the native `sh' on OpenBSD
| 2.7 `\"' expands to `"' in here-documents with unquoted delimiter. As
| a general rule, if `\\' expands to `\' use `\\' to get `\'.
but I still got bitten by it on Tru64 4.0D which fails a few tests
without this patch. Pushed. Enough bugfixing for today.
Cheers,
