copies: split up _chain() in naive chaining and filtering steps The function now has two clearly defined steps. The first step is the actual chaining. This step is very cheap. The second step is filtering out invalid copies. This step is expensive. For changeset-centric copy tracing, I want to do the filtering step only at the end. This patch prepares for that.

cHg
===

A fast client for Mercurial command server running on Unix.

Install:

$ make
$ make install

Usage:

$ chg help # show help of Mercurial
$ alias hg=chg # replace hg command
$ chg --kill-chg-daemon # terminate background server

Environment variables:

Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:

* configuration files are reloaded automatically by default.
* CHGHG or HG specifies the path to the hg executable spawned as the
background command server.

The following variables are available for testing:

* CHGDEBUG enables debug messages.
* CHGSOCKNAME specifies the socket path of the background cmdserver.
* CHGTIMEOUT specifies how many seconds chg will wait before giving up
connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60
