annotate srogue/rooms.c @ 282:8b6aba552f6f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Excise md_putchar(). The function wrapped the standard putchar(), doing nothing beside discarding the return value. That could cause problems with tputs(), which expects an int to be returned.
