Fix coding style violations reported by pycodestyle. This is
mostly a matter of reformatting code, particularly to eliminate
over-long lines. I also rename one variable ("l" is considered
visually ambiguous) and change a bare "except" to explicitly
catch all exceptions.
There are three types of error or warning remaining:
- debian/bin/...: E402 module level import not at top of file
Scripts in debian/bin need to modify the import path before
importing from debian/lib/python.
- E127 continuation line over-indented for visual indent
This seems to be a false positive. pycodestyle doesn't seem to be
happy with any level of indent (including 0) on a continuation line
in a "with" statement.
- debian/lib/python/debian_linux/debian.py:15:2: W291 trailing whitespace
This is a false positive. The trailing spaces are in a long
string and are intentional.
This fixes some of the problems dch was causing:
- Putting the stable log in the wrong place
- Updating the date unnecessarily
Change stable-update.sh to be a wrapper for stable-update.
Delete ckt-stable-update.sh; if we need it again in future, it can be
implemented more cleanly as part of the new script.
