- wrapping the path strings in quotes prevents interpretation as multiple files
  or paths if there are whitespaces in the path.

On Ubuntu systems, /bin/sh is actually "dash". "pushd" and "popd"
don't work with "dash". So we now use "cd" instead, thus lowering
requirements for shell.

This defect was causing "unknown" svn version in logs when jack was
build using dash.
