3c8a7990 - Emit `{}` around custom names followed by a regexp group. (#145) (#152)

Emit `{}` around custom names followed by a regexp group. (#145) (#152) * Emit `{}` around custom names followed by a regexp group. (#145) This change fixes another case from #145. Here we need protect a `:foo` group with `{}` braces if its followed by a matching group that may be expressed as `(bar)`. Without this protection the second group may be interpreted as a custom regexp for the first group. We want to generate `{:foo}(bar)` and not `:foo(bar)`. For the most part this change corresponds to this chromium commit: https://chromium-review.googlesource.com/c/chromium/src/+/3315419 Note, however, this spec change includes an additional fix to check for the next part being a segment wildcard. That additional check will need to be added to the implementation in another change. * Apply suggestions from code review Co-authored-by: Domenic Denicola <d@domenic.me>
