When making sed's command-line flags portable, don't split on $@ before parsing it, as this won't preserve the original string which needs passing to sed unmodified if it's never had to be changed.

When massaging sed command strings, to handle the differences between "-i ''" not meaning the same thing on non-BSD systems, this previously used a bashism to determine the positional arguments. Instead, defer to using a loop which doesn't rely on bashisms.

Remove erroneously-placed backticks when describing a lack of GNU coreutils.

Don't rely on $OSTYPE being available, which it isn't in strict POSIX mode. Ubuntu's sh is often alised to dash, and hence this fails. Instead, default to using the output from 'uname'.

When running tests on non-Linux systems, it was just assumed that GNU coreutils had been installed. This meant that the wrapper commands for date/ln on those systems always had gdate and gln installed. Rather than assume that, check to see if the GNU coreutils versions as present, and if not echo a warning.

PLATFORM is populated when running via `./configure && make` but this isn't guaranteed if an individual test is run directly, such as `regress/cmdline/tag.sh`. In such cases, PLATFORM will be empty, but we still want to use it. Since we test for non-linux values, only set PLATFORM if we're running on Linu so that the correct commands are used.

This brings the rest of the regression test scripts in line with patch.sh.

GNU sed doesn't like "-i ''" which on BSD means to not keep backups around. Scan for "-i ''" and replace with just "-i" which will use the filename given to sed just fine.

Ubuntu's default shell is dash, when using /bin/sh. The portable nature of got is such that "$OSTYPE" to determine the host type (linux, bsd, etc.) is bash-specific and is not part of POSIX. autotools already provide a mechanism for determining the underlying platform type, and PLATFORM is already a subst value. Therefore, let the -portable parts of the regress test-suite use $PLATFORM to look at the underlying OS type. The tests themselves already expect /bin/sh to be POSIX-compliant in all other areas, so there should be no need to change the #! lines.

In order to portably handle the difference in how 'sed -i' works between *BSD and Linux, provide a wrapper to invoke the underying system sed(1) based on which OSTYPE is in use.

To minimise the amount of churn between the difference in date(1) and ln(n) semantics, use gdate and gln from coreutils.

We need to do this because newer versions of Git support an arbitrary default branch name which can be set by users. We don't want tests to fail when this option is used. pointed out by Thomas Adam

Create automatic "backup" references which ensure that objects from the pre-rebase or pre-histedit state remain in the repository. A new -l option for 'got rebase' and 'got histedit' lists old commits. This makes it easier to recover from botched rebase or histedit operations. Removal of such objects currently requires got ref -d and git-gc. This will be made more convenient in the future. testing and ok jrick
