{{{hd .hgtags}}} shows that my last character (on linux) is '0a' (line feed). I don't know whether this is because I've cloned from a windows svn+hg clone.

    Pull request rejected ;( (for good reason).

    I've done what I can for now... identifying and fixing this issue satisfies my needs; to write test cases I would want to know exactly how this was caused.

    Which will probably happen eventually once I see other people's OS behaviour with new and/or corrupted repos.

    I have absolutely no idea how to reproduce this. I suspect it comes from a bug in .hgtags generation which may have been fixed since then: - Tags generated on hg side have no effect on subversion, do not have converted revision information and are ignored by rebuildmeta. At first I thought I could trick rebuildmeta by creating a tag on the hg side and overwriting it on subversion side but the parent resolution is correct and the first tag file ignored. - Tags brought from subversion are theorically sanitized before being serialized into a .hgtags. There might be bugs here but unless there is a clear report I see no reason to harden the reading code.

    So closing unless someone knows how to reproduce this.
