I needed something like the following to get the tests to pass.
If you like it, squash it into 5/6.

Subject: [PATCH] t6017: use 'tr -d' to strip spaces from 'wc -c' output

The previous use of 'grep -o "[0-9]*"' was producing an empty string
(GNU grep 2.5.1 on Mac OS X 10.4.11). Additionally, since 'wc' echos
its filename arguments when stdin is not the source, the 'grep -o'
might have also extracted additional decimal strings embedded in the
filename (a SHA-1 hash value).

This 'tr -d' style is used in git-filter-branch.sh, and t6003.
Another alternative (in t1006) is to use 'sed' to strip off the
leading spaces.
