Subject: [PATCH 14/14] t{3032,6038}-*.sh: Allow SED_BIN_OPT to override the -b sed option
Message-ID: <4D07BAE8.6070904@ramsay1.demon.co.uk>

```

Some older versions of sed (eg. v3.02) do not understand the -b
(--binary) option. However, these versions of sed may have an
equivalent option we can use to request binary mode processing
(eg. -c or --nocr).

I nearly didn't send this patch, since my MinGW sed is somewhat old, and
most people would not have this problem. (Note I *think* I installed
using msysGit-fullinstall-1.6.4-preview20090729.exe)
So, feel free to drop this patch...

It is unclear who is supposed to feed you SED_BIN_OPT.

Perhaps a patch to add an insn like "If you have an ancient sed, export
SED_BIN_OPT=-c before running tests" to t/README is also necessary to go
together with this change.

```

Yes, you are right. I had such a change to t/README but it was mixed in with
another patch to document other such variables which was incomplete. (see my
previous mail in response to your comments on patch 4/14).

Also, I was half expecting you to drop the patch, because I thought I was in
the minority with an old sed; however, it seems I'm not that unusual after
all ... ;-)

ATB,
