st: column names in e(b)

[Keith Dear <keithdear4@gmail.com>]

A post-estimation program I wrote for poisson regression failed when a
colleague tried to use it after -regress-.
The reason turns out to be the different names used in the coefficient
matrix e(b) in each case:

. qui poisson y x
. mat list e(b)

e(b)[1,2]
             y:          y:
             x       _cons
y1    .0236604  -.69706433

. qui regress y x
. mat list e(b)

e(b)[1,2]
            x      _cons
y1  .01192463  .49802156

So -poisson- includes the equation name (depvar) in the column names,
while -regress- does not.

Is there a reason for this difference?
Is there a general rule?
Is there a standard way of handling this? (it wasn't hard to fix this
particular case, but in general?)
Where can I read about it?

Thanks,
Keith
