WIP patch

This patch reuses variable_check() and as a bonus fixes the declarations
of the subroutine versions.  It also checks the length of the character
argument if known at compile time - it must not be 0.

It does not accept the testcase in comment#4.  This is possibly something
that could be handled in variable_check().
