devtools: fix lookup commit fixing a fix of many commits

There was a bug when looking at a commit fixing a commit which
itself was fixing many commits:

% devtools/git-log-fixes.sh 12ee45a36~..12ee45a36
devtools/git-log-fixes.sh: 96: local: 5499c1fc9baa: bad variable name

In this case, the list of commits was not quoted in variable assignment.
