Matthias Grob 2c56ceec93 astyle: switch condition to empty string check
Thanks to @bkueang 's review comment I switched to an explicit check for
an empty sting instead of a condition that could be theoretically true
in other cases and is less readable.

Type "man test" on your terminal to read up what -n stands for.
