Re: [PATCH v9 3/8] cat-file: split test utility functions into a separate library file

About the commit subject, maybe something like the following would be
a bit shorter:

t1006: split test utility functions into new "lib-cat-file.sh"

This might be a bit misleading as leading spaces are removed from the
output from `wc -c`, not from the string.

+strlen () {
