hooks: allow Unix style environment variables on external Windows hooks This will help making common hooks between Windows and non-Windows platforms. Having to build the shellenviron dict here and in procutil.system() is a bit unfortunate, but the only other option is to fix up the command inside procutil.system(). It seems more important that the note about the hook being run reflects what is actually run. The patch from last summer added the hooks on the command line, but it looks like HG_ARGS has since learned about --config args, and the output was just confusing. Therefore, it's now loaded from a file in the histedit test for clarity.

'''http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs
platforms to provide authentication information for HTTP access. Configuration
entries specified in the auth section as well as authentication information
provided in the repository URL are fully supported. If no prefix is specified,
a value of "*" will be assumed.
By default, keys are specified as::
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be
requested interactively.
A configuration section is available to customize runtime behavior. By
default, these entries are::
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The
mountpoint entry defines the path to the factotum file service. Lastly, the
service entry controls the service name used when reading keys.
