Target version:
ruby -v:
1.9.2-p180 revision 30909


I am using 1.9.2-p160 revision 29036

If there are an odd number of quotation marks inside a regular expression, the syntax highlighting breaks, continuing the regular expression color until another quotation mark is found.

method /"(["]*)"$/ do |arg|

continues regular expression syntax color until quotation is matched

Syntax continues to work correctly with parentheses around the method, such as
method(/"(["]*)"$/) do |arg|

Searching led me to a related bug that was fixed:

This is kinda-fixed in the Emacs trunk, provided that "method" is one of the names in the list ruby-syntax-methods-before-regexp.
Otherwise, the whole regexp literal isn't recognized in the first example. It should be obvious, the string-like highlighting would only start after the " character.
