The 'tar' utility is not available on all platforms (some only support
'gnutar'). An earlier commit created a work-around for this problem,
but a better solution is to eliminate the use of 'tar' completely.

mktemp is not available on all platforms. Instead of littering the code
with a work-around, this commit replaces mktemp with a one-line Perl
script.

The 'git difftool' allows the user to view diffs using an external tool.
It runs a separate instance of the tool for each file in the diff. This
makes it tedious to review changes spanning multiple files.
The 'git-diffall' script instead prepares temporary directories with the
files to be compared and launches a single instance of the external diff
tool to view them (i.e. a directory diff).
The 'diff.tool' or 'merge.tool' configuration variable is used to specify
which external tool is used.
