Ready for when they're approved. Just have to wait two months :-)

John, if you split this patch in file (whitespace) restructing and the actual addition, the first can be applied now, and the latter becomes a whole lot simpler (smaller), increasing the chance it still applies this autumn...

Done

OK, the first patch is now applied to master. Thanks!

There is news from IUPAC, I heard: https://twitter.com/Larsohrstrom/status/803871908236296192

@johnmay, I can resolve the conflicts here... unless you want to rebase the patches yourself? Plz let me know...

I'll fix the conflicts... actually bad names but they knew (read the document).

Ts is normally used for Tosyl, they say a chemist would never confuse the two but of course teaching a computer that is a little more tricky... well other than to just banning it's use.

Nh is more fun... consider [Nh] ins SMARTS used be aliphatic nitrogen with one implicit hydrogen. I think probably the fix here is ban the bottom rows from SMARTS symbols and suggest using '#' syntax instead.

Oh, wonderful points! @rajarshi, what do you think? Should we invite @johnmay for a JCheminf Commentary (http://jcheminf.springeropen.com/submission-guidelines/preparing-your-manuscript/commentary) to write up the implications to cheminformatics (i.e. outlining some of the (open) standards that need updating? I'd be happy with even shorter than 800 words...

Yes, that would certainly be welcome. @johnmay raises a good point - standards committees might consult with informatics to ensure that they're standards don't impede informatics handling
