branch: master
commit b391ee84886ce2a024f9e958b2cc2c9d30aa921f

    Table: Completion, bash4+ long option no space
    
    Until now, we used the 'nospace' option of 'complete' to handle
    suggestions for options which had an '=' inside them. With this commit,
    if the command being completed contains '=', no spaces will be appended.
    
    This only works in bash4+ for '[[' and 'compopt' are used within this
    approach. Let's just keep this here and look for a workaround in future
    commits.
    
    TODO: Work on compatibility for bash older than version 4.
