Summary: is there a convention for the in circuit programming pins?

Previously, with my hacking on the 8-pin and 18-pin DIP PICs, I've been
happy to pull the chip and place it into a programmer.  Now that I'm
embarking on a 40-pin DIP, I'd prefer to place a set of header pins on
my PCB and connect it to one of my programmers.

The DT-001 has ten pin, two rows of five, header position on the PCB.
My other programmers, by DIY electronics, don't have any such thing.

Unfortunately, due to my distance from any form of electronics shop, I'm
going to do things based on the parts I have ... and I only have single
row headers handy.

I've also realised that I have to somehow allow the programmer to power
the PIC while preferrably not powering the rest of the circuit.  I could
have a shorting header to enable or disable the propogation of Vdd to
the rest of the PCB from the PIC, but some day I'll forget.  If I use a
pin on the ICSP header at the PCB as the supply in to the PIC, then I'm
less likely to forget to replace the shorting header.

That makes the pins I need on the ICSP header ...

- Vdd from PCB
- Vdd to PIC
- Vss
- MCLR (not)
- PGD
- PGC
- PGM (do i really need this?)

And I would replace the cable with a shorting header between the Vdd's,
in order to RUN.

So, anyone seen a convention for the pins on a single row ICSP header?
