Optimization: Put grep -v empty task filter inside sed.

No need to spawn off another process for this; we can do this inside the sed command that joins the task numbers with the task text.

Note: The sed on OS X does not understand the \+ bound, only in the form of + when used with -E. Instead, I chose to fall back to the \{1,\} basic regexp, in the hope that it is very portable, and to avoid introducing extended regexps to the script.
