This isn't a Trac instance; it's a Pagure instance.

This PR is hard to review because you've combined so many different changes into a single commit.

Rename and format markdown files

Did you rename them? I'm unfamiliar with Pagure but although I see that you reformatted files like README and THANKS to add markdown syntax, it doesn't look like you renamed them to add the .md suffix.

I see you also removed hard newlines. This makes the raw files harder to read in a web viewer like Pagure's since it does not add its own word wrapping. It also makes diffs harder to read. You might want to keep the hard newlines.

Covert output path to unix on cygwin/msys

I could not find the lines of code related to this change. Did you mean "Convert" instead of "Covert"? If so, it appears in three places in the code and in the commit message.

And whereas Trac used the term "ticket", Pagure uses the term "issue".

Thank you for the review; I have to split it into multiple commits and return the hard newlines; you are right.

I could not find the lines of code related to this change.

I've merged previously opened PR and am adding it to the ChangeLog. I meant Convert; thank you for noticing the typo.

I will rebase it with changes.

Everything should be fixed now, and the commits are more readable for better review.
