getting pull/push/fetch url

Hello,

for my app, i need to be able get remote urls (fetch/pull/push) so
that i can derive some information from those, e.g. pull url netloc
from which i derive where other custom endpoints (binary file storage)
related to the remote git repo is located. This is just one example. I
am also using fetch url to store it into the composed package that i
generate by the app.

...And I also want to support git down to 1.7.1 (maybe i could live
with 1.8.3, not sure now)

Now, the problem is that getting those urls (fetch/pull/push) doesn't
seem to be an easy task. Currently i have the attached scripts to do
that. But i noticed that older gits like 1.7 use origin as a fallback
for pull url whereas the newer raise an error.

My question is if there is a better way to determine the urls that
would be backward compatible and easier than what i am doing right
now.

I could probably tweak my app to only use fetch url but then i won't
support triangle workflow so i would like to know if there is some
better option.

Thank you
clime
