Tags are much better for referring to specific parts of a file and line numbering is better done by a post-processing tool such as cat -n or producing a two-column HTML <table>.

2019-02-17Simplify temp trap in upJune McEnroe
2019-02-17Add line numbers to hiJune McEnroe
Renames previous -n option to -m to stay consistent with cat -n. Prefixing lines with line numbers affects where the first tab indent ends up relative to the text above it. Not sure if it's worth fixing somehow.
