When creating a ChangeLog entry for *.m4 files, we should mention the Autoconf
macro name. git's default heuristic is to look at the previous line that
starts with a non-whitespace character. Unfortunately, in our *.m4 files, we
have C code and changequotes command frequently indented at column 0; this
kills the heuristic. This patch adds another heuristic, suitable for *.m4 files.
