That appears to be a bug in the checker.  This isn't a C array
expression, but an argument in lispy vector notation, so it should be
separated by a space.

Yeah, the checker fails on machine descriptions currently, i should have mentioned that, sorry!

The .md change above is gone by now.
No reason to resend the patch, just fixing it before you push it is fine, once ACKed (although such patches usually counts as obvious).

Many thanks for the quick tweak!

There are still some sync.md changes (comment whitespace/function whitespace changes).

Thanks for the help with this - still getting the hang of pushing my own changes!
