[9fans] hget in proxy environment

[<vdharani@infernopark.com>]

hi,

i tried to install plan9 using network method but couldnt. i noticed a
couple of problems:

1. looks like hget is used to download the distribution. and looks like
hget wont work where a proxy server serves the http requests (port 80 is
disabled).

2. there was no indication that distribution failed. the installation
proceeded to the next step as if things were fine.

3. in the next step where it asks to locate the distribution directory, it
loops till you locate a directory where the distribution is found. you
know you need to do something but it doesnt let you correct the problem.

the issues here are minor and can wait to be fixed. however, i think it
should be easy to fix hget so that it works well with proxy environment.

any help appreciated.

thanks
