Complex string incorrectly highlights as quoted symbol about vim-ruby HOT 2 OPEN

No fix yet.

from vim-ruby.

Another example I ran into that hits the same issue, I think:

output: {
  'loglevel' => 'fatal',
  vf: 'scale=\'min(400\, iw):min(400\, ih)\':force_original_aspect_ratio=decrease',
}.freeze,

I managed to patch it locally by adding a check for the lack of \ before ', but that's really a workaround

-syn match rubySymbol "'\%(\\.\|[^']\)*'::\@!"he=e-1 contains=rubyQuoteEscape,rubyBackslashEscape,rubySingleQuoteSymbolDelimiter
+syn match rubySymbol "'\%(\\.\|[^\']\)*'::\@!"he=e-1 contains=rubyQuoteEscape,rubyBackslashEscape,rubySingleQuoteSymbolDelimiter

It's weird that it's even trying to highlight ...min(400\, ih)\':force_... as a symbol, it shouldn't be contained inside one. I don't know.
