heads: show closed heads only when --closed is passed Add a --closed (-c) option to 'hg heads' to show all heads and change the default behavior to refrain from showing fully closed branches. Enhance 'hg heads <branch>' so that: * default: displays normal & inactive heads, not closed heads * --closed: displays normal, inactive & closed heads * --active: displays only normal heads * both --closed and --active: displays normal & closed heads only

localrepo: set heads and branchheads to be closed=False by default The heads(...) and branchheads(...) functions will now only return closed heads when explicitly asked for them. This will cause 'hg merge' to have better behavior in the presence of a branch that has closed heads when no explicit rev is passed.
