A couple of tests use perl only for generating a string of
N characters long. Instead of requiring perl to run a few
tests, use shell built-in commands and don't repeatedly run
a separate subshell just to get a string of characters.

construction which fails on strict POSIX compliant shells, such as
dash.

Could you please point out which constructs it is unhappy with? I had
an earlier version of the patch using a different mechanism, but then
updated it after feedback from Lukas.
