When running on a Debian-based system, such as Ubuntu, /bin/sh is provided by DASH, not BASH.
This means that BASHisms are unsupported. There are two BASH variable substition instances within
the code of xdg-settings.in that cause KDE users to be unable to find the current web browser
because the script dies when hitting this unsupported code.
- Replace
${variable:0:1}withprintf-based equivalent.
Fixes #10
