src: Don't escape completion candidates with \

Completion candidates are currently escaped with a backslash `\`
character, which leads to ugly interactive commands on the prompt,
especially when they contain space characters.

This commit makes completion candidates be escaped by simple quoting.

Examples:

    candidate\ with\ spaces
    \%opt{foo}
    \"dquote
    \'quote

become:

    'candidate with spaces'
    '%opt{foo}'
    '"dquote'
    '''quote'
