annotate rogue5/misc.c @ 87:f871cb0539d3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't set the player's ISRUN flag. rogue4 and rogue5 set the player's ISRUN flag upon exit from sleep or holding. This is apparently supposed to indicate that the player can move again. What it actually does is make it harder for monsters to hit the player, until the flag is reset. As this behavior makes little sense and seems like a cheat, it has been deemed a bug and removed.
