    Always offer completions (workaround for company issue #476)
    
    The issue appears clearly when one wants to insert unicode symbols with
    short LaTeX names, such as ‘\Cap’, ‘\wp’, or ‘\wr’. The problem is that
    company-mode closes its popup if there is only one completion available,
    and it has been typed in full. In that case, even running
    ‘company-manual-begin’ has no effect; the only way to insert the
    corresponding unicode symbol is to remove the last character of the
    symbol, and to run ‘company-manual-begin’.
    
    This commit introduces the workaround discussed in
    https://github.com/company-mode/company-mode/issues/476: we add a space
    at the end of each symbol in ‘company-math-symbols-unicode’, to ensure
    that the user can always use ‘RET’ to insert Unicode symbols.
