The option --show-uncovered does not show the correct line numbers

[simon-bennett-aql]

The following command produces different output between the console and the html report.
diff-cover --show-uncovered --html-report diff-report.html coverage.xml

Specifically, the line number is correct in diff-report.html, but incorrect in the terminal output.

This issue is plaguing us also so I had quick look.

It seems that pygment's TerminalFormatter (https://pygments.org/docs/formatters/#TerminalFormatter) is being used in Snippet.terminal() to format the lines for a terminal (colours et al).

This formatter however doesn't support the linenostart option being passed to it, resulting in line 1 always being the starting number.

@GertBurger
Is there any progress on this? Would be great to have lines on Markdown and terminal templates if possible.

Not that I know of, the last I heard was what you saw in my PR on pygments.
