[PATCH] test for add with non-existent pathspec

[Chris Packham <judge.packham@gmail.com>]

Add a test for 'git add -u pathspec' and 'git add pathspec' where
pathspec does not exist. The expected result is that git add exits with
an error message and an appropriate exit code.

This adds 1 expected failure to t/t2200-add-update.sh.

If anyone feels like pursuing this heres a patch to two simple tests around
this behaviour. I made an initial attempt to change builtin-add.c to print an
error message and set the exit code to a non-zero value but my naive attempt
broke the normal usage of 'git add pathspec'.
