[PATCH] push: Alias pushurl from push rewrites

[Rob Hoelz <rob@xxxxxxxx>]

git push currently doesn't consider pushInsteadOf when
using pushurl; this tests and fixes that.

If you use pushurl with an alias that has a pushInsteadOf configuration
value, Git does not take advantage of it.  For example:

[url "git://github.com/"]
    insteadOf = github:
[url "git://github.com/myuser/"]
    insteadOf = mygithub:
[url "git@xxxxxxxxxx:myuser/"]
    pushInsteadOf = mygithub:
[remote "origin"]
    url     = github:organization/project
    pushurl = mygithub:project
