Add --line-number option to hg annotate (issue506)
Line numbers are separated from the last annotation element with a colon,
like with many other commands, e.g. (hg) grep or compiler errors.
Idea and tests by FUJIWARA Katsunori.
#!/bin/sh

echo "Is there an error message when trying to diff non-existing files?"

echo "Is there an error message when trying to add non-existing files?"
