I am using Hugs 1.4, Version 970410, Windows 95. Below, are two simple
functions, testa, and testb, followed by a copy of a session. The first
evaluation of 'testa 2' results in two blank lines following the 'Program error:
...' line. The second evaluation of 'testa 2' results in a single blank line
following the 'Program error: ...' line. Next, evaluation of 'testb 2' results
in a quote mark '"' on a line by itself followed by the 'Program error: ...'
line.
Is this how one would expect Hugs to operate?

testa 1 = putStr "one"
testa _ = error "argument value of 1 required"
testb 1 = "one"
testb _ = error "argument value of 1 required"
