field buffer vs visible field size

[tjareson]

Hello,

I'm using the ncurses forms a lot and have sometimes the situation that 
the string I'm assigning by pointer  to a field with set_field_buffer is 
bigger than the field size (including off screen rows), which leads to 
the result that characters are cut off at the end when the field is 
displayed.
(which is the required behavior - I don't want to show the seconds of a 
time stamp, so I made the field 3 characters short than the content)

I'm only not sure if that cause any potential problem of memory 
corruption within the forms library?
(As these kind of problems do not necessarily need to cause an error 
everytime)

Of course I could check the field length and shorten the assigned string 
accordingly, but would like to safe the code if it is not really necessary.

Any hints?

kind regards
Tjareson
