and the sizeof operator, missing empty lines, void casts, extra empty lines.
Checked by: diff on make *.o lst.lib/*.o
Submitted by: Max Okumoto <okumoto@soe.ucsd.edu> (partly)
to var_modify.c, for readability. constify some low hanging fruit (string

the private strstr(3) implementation, while changing string code.
Tested by: lots of successful make buildworld.
