Subject: [PATCH] Fix bash-completion treatment of existing arguments
 containing spaces.

Currently a few things aren't quoted properly, such that when the function is performing completion by e.g. suggesting an output filename by taking the input filename and changing its extension, if the filename contains a space, all but the last space-separated component will get cut off (e.g. "flif -e haggard\ beavis\ egg.png " + TAB will fill in "egg.flif" as the next argument).
