This code %g is preliminary.
Fixed some code style issues to match the current code style.
Added regression tests and help file updates to printf and strprintf.
Fixed use of magic number -4: using -P instead.
Noted two problem areas with XXX comments in qio.c:
1) need a qprintfg function
2) re-write to not modify conf->outdigits
