Subject: [PATCH 2/6] dax: remove leading space from labels

No functional change.

As of this commit:

commit 218dd85887da (".gitattributes: set git diff driver for C source code
files")

git-diff and git-format-patch both generate diffs whose hunks are correctly
prefixed by function names instead of labels, even if those labels aren't
indented with spaces.
