[TS-23] Tasksh throws errors on unescaped parentheses

[taskwarrior]

I had expected that an interactive shell for task would be more forgiving with respect to unescaped special characters, but tasksh choked on parentheses:

tasksh> add This is a task that includes parens (see I told you so)
[task add This is a task that includes parens (see I told you so)]
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `task add This is a task that includes parens (see I told you so)'

I think this just requires re-escaping anything that might need it before issuing the taskwarrior command.
