annotate xrogue/main.c @ 177:7bdac632ab9d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
srogue: fix an uninitialized variable. In wanderer(), if rp == hr, the loop could test ch before its value has been set. Initializing ch to '-' now causes the loop to repeat until a location is found.
