Octal escape sequences can be as short as 2 bytes (\0, ..., \7),
therefore they allow one to generate shorter files than hex escapes, for
the same resource contents. The line lengths won't be as even, but this
is purely cosmetic, virtually no one will ever read the resource data
string literals, so this is quite a negligible drawback compared to the
advantage of using less space in the Git repository every time resource
files are committed.
