[PATCH v3 1/2] parsemail.py: Avoid skipping patches when parsing

[Jose Lamego]

Hi Damien,

Glad you verified this, let me share my findings: I checked the original
patch [2] that included the following changes but that I wrongly cut
after finding that they collide with testGitPullWithDiff test in upstream:

     def find_pull_request(content):
        git_re = re.compile('^The following changes since commit.*' +
    - '^are available in the git repository at:\n'
    - '^\s*([\S]+://[^\n]+)$',
    + '^are available in the git repository at.*:'
    + '^\s*([\S]+://[^\n]+)',
         re.DOTALL | re.MULTILINE)
        match = git_re.search(content)
	if match:

this patch is currently implemented both in our Open Embedded Patchwork
[3] and in a staging instance that I use for tests. Both these instances
are running Patchwork 8904a7dcaf959da8db4a9a5d92b91a61eed05201

I just verified that the staging instance do skip this same email if I
revert parsemail.py to:
	'^are available in the git repository at:\n'

I previously had verified that some messages were skipped when
parsemail.py contained:
	'^\s*([\S]+://[^\n]+)$'
but unfortunately I couldn't find an example message right now.

I'm assuming that this behavior is caused by something (maybe
parser.py?) that is already fixed/updated in patchwork's upstream, but
not in our version, then the patch is still needed for us.

so, as you already pointed out, this patch can be superseded as it is
actually not needed when using latest patchwork version.

This also adds to the list of why we need to upgrade our patchwork.

Sorry for the long message, but I figured that this would be of interest
for you.

Regards
Jose
