This patch adds support to multi-line changes. That is, if one has a line
in a changelog like
- Do a thing but
it spans multiple lines
Using Series-process-log sort would sort as if those lines were unrelated.
With this patch, any change line starting with whitespace will be
considered part of the change before it.

Series-process-log: sort, uniq
- This tells patman to sort and/or uniq the change logs. It is
- assumed that each change log entry is only a single line long.
+ This tells patman to sort and/or uniq the change logs. Changes may be
+ multiple lines long, as long as each subsequent line of a change begins
+ with a whitespace character. For example,
+
+- This change
+ continues onto the next line
+- But this change is separate
+
Use 'sort' to sort the entries, and 'uniq' to include only
unique entries. If omitted, no change log processing is done.
Separate each tag with a comma.
