Does testing of the "roundtrip" way doesn't work on windows?

It seems that _findfirst doesn't accept a file name including a tab or newline.

Thanks. I don't know the code logic well but the test cases looks good to me.

I think we still need to write about how {tagfile} is printed in the manual, according to how it's actually implemented, so a client tool knows how to get the actual path.

Another problem is how could a client tool know if readtags has this patch. It's hard to do without a version number.

@AmaiKinono Thank you for reviewing.

I will write it in "EXCEPTIONS IN UNIVERSAL CTAGS" or somewhere in tags(5).
I would like you to review the text I will add. I opened #3584.

I agree with you. I opened #3551.

[masatake]

I wonder whether we can use the same version number in ctags and readtags.
