The function get_commit was using the global merge variable instead of
the local commit variable. Therefore it returned the wrong commit
subject for merges without subject.
There is curently a merge commit without a subject, which leads into a
traceback in the changelog script.
The merge information provides the commit hash, which is now used to get
the subject later on using the generated commits hash.
This scrip can be used to generate the changelog text for a new
ansible-freeipa release on github.
usage: Usage: changelog [options] [<new version>]
optional arguments:
-h, --help show this help message and exit
--tag TAG git tag
If the script is used without a givn tag, it will show all the changes since
the last tag. If a tag (this can be a also a commit) is given, then all
changes since this commit are shown.
