Documentation:
Qualification of END statements according to the matching block start.
For example, change the END that closes an IF block to END IF.
If the block has a label, add it as well (unless `f90-smart-end-names'
says not to). Allowed values are `blink', `no-blink', and nil. If nil,
nothing is done. The other two settings have the same effect, but `blink'
additionally blinks the cursor to the start of the block.

You can customize this variable.
