+
+ Fixes a bug reported by Greg Hunt <greg@firmansyah.com>.

+
+ Continue reforming procedure execution. In this phase, get rid of
+ the output code for SPLIT FILE groups in procedure.c, which really
+ shouldn't be doing any output. Move it into the individual
+ procedures instead. This also adds some flexibility.
