Using git with http behind proxy with authentification?

Hi,

because I'm sitting behind a firewall I have to use cogito/git using 
http. But http proxy needs special authentification with user & 
password. It seems to me that this isn't supported with recent cogito/git?

In the past, for bk I used

$ export http_proxy=http://user:password@someproxy.some.where:8080/

which worked. But no luck with cogito/git.

Looking into recent cogito/git, the reason for this seems to be that 
cogito/git uses a combination of wget in scripts and curl in compiled 
executables. Having a look to cg-pull script, this script uses wget. 
Then, it calls git-http-pull if it thinks that http should be used. 
Looking at http-pull.c shows that there curl is used for http access. If 
I understand it correctly from man pages, wget understands user:password 
syntax of http_proxy environment, but curl doesn't. As I understand it 
curl understands only 'someproxy.some.where:8080' and wants the user and 
password given as parameter of curl_easy_setopt. The curl_easy_setopt 
man page tells something about CURLOPT_PROXYUSERPWD parameter.

Any ideas?

Many thanks

Dirk
