Bash completion for project names

[muxina-credo]

I have been defining projects with a longer name as a string:

task add project:'a new project' foo

When I'm managing tasks I try to write project: and then try to autocomplete with the TAB key. It appears the string split into words: a, new, project. Which makes it impossible to select projects with longer names using auto-completion.

Can anyone help with some suggestions?
