comparison tests/mini/foreach10.d @ 1185:8baf611f0009

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix nested references to 'ref' foreach variables. These "walk around" the array being iterated over, so they're a bit trickier than other variables to get right.
