allow selective enabling of bash-completion modules

[jabronson@…]

Currently there is no way to selectively enable bash-completion modules; ". /opt/local/etc/bash_completion" causes all 149 modules in /opt/local/etc/bash_completion.d to be loaded and results in an unnecessary slowdown in shell startup time (e.g. 0.635s on my new Macbook Pro when the disk cache is cold (0.224s when hot)).

Other bash-completion distributions provide a facility for selectively enabling modules (e.g. eselect bashcomp enable ... on Gentoo). Could MacPorts make use of their prior art somehow?

Now that MacPorts has subports, the bash-completion port could be broken into subports that could be installed separately...

The original ticket description referred to Gentoo's eselect bashcomp which makes a per-user configuration possible. The slow shell startup has been improved in the upcoming bash-completion 2.0, of which the current beta version is available for testing in the bash-completion-devel port.

bash-completion and bash-completion-devel are now both version 2.0 as of r95135. The shell startup is very fast now, so there should be no need for selective enabling of completions.
