Bash Completion for Aliases

The Problem and its Solution

Suppose you have an alias like this:

alias gc='git clone'

If you'll type gc -- followed by a [TAB] you won't get any bash completion for the available options.

To overcome this problem you can use script in file alias_completion.sh.

This script shouldn't be called normally, but sourced (use either source alias_completion.sh or . alias_completion.sh) after the aliases are defined. IMHO the best way is to put it at the very end of file ~/.bashrc.
