[GUILT v4 16/33] Fix backslash handling when creating names of imported patches.

[Per Cederqvist <cederp@opera.com>]

The 'echo $s' construct sometimes processes escape sequences.  (This
happens, for instance, under Ubuntu 14.04 when /bin/sh is actually
dash.)  We don't want that to happen when we are importing commits, so
use 'printf %s "$s"' instead.

(The -E option of bash that explicitly disables backslash expansion is
not portable; it is not supported by dash.)
