[PATCHv2 5/9] branch, commit, name-rev: ease up boolean conditions

[Stefan Beller <stefanbeller@googlemail.com>]

Now that the variables are readin by OPT_BOOL, which makes sure
to have the values being 0 or 1 after reading, we do not need
the double negation to map any other value to 1 for integer
variables.
