Word has it some really old shells nobody would use to compile Linux on
interpret "" not as an empty argument, but as a non-existing argument,
turning if [ "" != "" ] into essentially if [ != ].
Doing x10 avoids the uncertainity whether shells might attempt to
interpret it as octal or not.
So far the interpretation..

Wonder what POSIX says about that.
