This makes t/no-tabs.t pass.
I'm responsible for some tabs in previous patches, so this
fixes mine also :)
Note that I find this test silly, but "dura lex, sed lex"...
Source common.sh from the parent directory if the global installation
isn't found.
This allows "make test" to succeed *before* the tools are installed.
Added to the repository. These are almost straight copies of the
previous hook scripts except they are now Debian-specific.
They also each log their start and finish and optional information
via the use of the ../common.sh file.
No major changes anticipated.
