Query interprets "].*>" pattern in attribute value selector incorrectly

[eis271828]

dojo.query("> [rowid='>thing']", "parentId") //works
dojo.quert("> [rowid=']>thing']", "parentId") // searches for "> [rowid=']> thing']" (note extra space, since the ']' character fools the attRe regex used in acme.js)

The trivial example above is not particularly important, but given that grids of various types can have a rowid attribute set based on any data, this does have real-world implications.

Given that no one has shown interest in creating a patch in more than a year, I'm closing this as patchwelcome. Please let us know if you would like to get involved in helping make this change to Dojo!
