Another problem caused by BSD v GNU sed, I think.

Oh, that again X-<.

Will patch up in a stupid-but-trivial way, unless somebody knows a
reliable workaround.

I no longer have a BSD handy to test, so I'd appreciate it if
somebody can do a quick sanity check.

Thanks.

Subject: [PATCH] t4055: avoid BSD/GNU sed incompatibilty issues

The 'a', 'i' and 'c' commands that take literal lines to be added
followed by backslash does not seem to work reliably on some BSD
systems.  Avoid it by having an extra line in a template file and
generate test vectors by deleting the line or replacing the line.
