Add bash_completion to contrib
Contributed by "Alexis S. L. Carvalho" <alexis@cecm.usp.br>
Attached is a file that implements bash completion for hg. Just
reading it from your .bashrc should be enough to use it - I think: I'm
using the /etc/bash_completion from debian and I'm not sure whether it
sets some important option.
It gets the list of commands, aliases and options from the output of hg
help and then adds some specific stuff - e.g. completing update with
tags; pull and push with path aliases and directories, etc.
