problems:
- It doesn't support filenames with spaces.
- It inserts a space after the filename when tab-completing in an
"svn" command.
- Many people find it annoying that tab-completion on commands like
"tar" only matches filenames with the "right" extension.
- Lluís reported bash apparently crashing on some tab completions.
We should probably make this optional, and maybe use a subset of the
bash_completion file in the bash distribution that works.
svn path=/nixos/trunk/; revision=20179
bash: BASH_COMPLETION_DIR: readonly variable
bash: BASH_COMPLETION: readonly variable
And in the non-interactive shell, we get:
/nix/store/654xcqk8h2a409mxsnsbnj5c0cp9mjhm-bash-4.1-p2/etc/bash_completion: line 75: shopt: progcomp: invalid shell option name
