bug#11047: 24.0.94; Hangs when creating buffer starting with multiple spaces and there exists buffers with multiple spaces

[Stefan Monnier]

Another possibility is that it's stuck in a pathological regexp-match
for partial-completion ("  b c" can turn into a regexp like " .* .*b.*
c" which will match "  a 1 a2 b c" in many different ways).
