--- Hi Pádraig,
thanks for your last response. Yes, I know that this seems to be edge case usage, but I also don't see that this may hurt anybody. So I've tried to make this patch complete, just to have it pushed it out. But feel free to consider it or not. I'll be fine with every decision :-) Best regards, Michael Changelog: v2: - added test and documentation v1: - initial submission doc/coreutils.texi | 7 +++++ src/split.c | 18 +++++++++---- tests/local.mk | 1 + tests/split/hexadecimal.sh | 65 ++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 86 insertions(+), 5 deletions(-) create mode 100755 tests/split/hexadecimal.sh diff --git a/doc/coreutils.texi b/doc/coreutils.texi index 7edd1b9..6232d6e 100644 --- a/doc/coreutils.texi +++ b/doc/coreutils.texi @@ -3243,6 +3243,13 @@ suffixes beyond @samp{99}.
