I assume Stefan just grabbed my naive suggestion hence why it checks
equality with a commit. So that's my fault :) Either of these may
not be enough though, since if you do 'git grep malloc v2.9.3^{tree}'
with this change the output prefix is 'v2.9.3^{tree}/' instead of the
correct prefix 'v2.9.3^{tree}:'
