Subject: The Light Up solver limits its recursion depth, so if it fails to find
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=4eb748a29c7fab6b666e9841297975d11d9681df;p=sgt-puzzles.git

The Light Up solver limits its recursion depth, so if it fails to find
a solution then it should not deduce that no solution exists. Change
wording of the error message returned from the Solve user action.
