legend.m: Code cleanup for cset c66467f74278. * NEWS: Wrap lines at 72 characters. Use two spaces after period. * legend.m: Document using "command" without function-style syntax. Rename "pos" to "loc" in documentation for input which specifies location. Hand off to __gnuplot_legend__ immediately if gnuplot is current toolkit. Use parentheses around condition in switch statement. Add semicolons to end code lines even when they do not produce output (set (...), continue, etc.). Remove trailing whitespace. Remove '...' line continuations when they are not strictly necessary. Add commas between items in arrays '[..., ...]' for readability. Use NaN() instead of nan().
