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.
