Ben Hutchings 7fb5a93645 kconfig/nconf: Fix hang when editing symbol with a long prompt 
commit 79e51b5c2d upstream.

Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters.  dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid.  It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.

The additions in the offset calculations also don't match the intended
size of the window.

Limit the window size and calculate the offset similarly to
show_scroll_win().

Fixes: 692d97c380 ("kconfig: new configuration interface (nconfig)")
