Caveats for switch trunk?

Hi Group,

i noticed that after i issued the 'switchport trunk allow vlan
a,b,c,d,e,f,g,h,i,j,k,l etc...'

the sh run display:

switchport trunk allow vlan a,b,c,d,e,f,g,h
switchport trunk allowed vlan add i,j,k,l etc...

Is there any specific reason why the IOS would append the 2 line with
the remaining vlans?

Is there really a limitation to how many vlans IOS can display in a
singular line?

It didnt really bother me until when i try to: switchport trunk allow
vlan a,b,c,d,e,f,g,h,Z

the sh run display:

switchport trunk allow vlan a,b,c,d,e,f,g,h
switchport trunk allowed vlan add Z

it apparently DELETE my vlans for i,j,k,l etc... for the 2nd line :(

Well i guess i learn it the hard way. BUT Is there really a limitation
to how many vlans IOS can display in a singular line?
