#4 Allow extended (programmable) bash completion

[Christian Reitwiessner]

It would be great to have gmrun complete the command line like
bash does with bash_completion turned on, i.e. the completion
depends on the command run, for example ssh's arguments
complete only to hosts, xpdf's arguments only complete to pdf files
and so on. One would need to use code from the bash project,
though, because the completion is highly configurable.
I could also think of two different tabs (perhaps tab and ctrl-tab),
one that uses bash_completion and one that uses normal
completion.
Would be great to have it ;-)
