graphlog: implement --follow-first log --graph --follow-first FILE cannot be compared with the regular version because it never worked: --follow-first is not taken in account in walkchangerevs() fast path and is explicitely bypassed in FILE case in walkchangerevs() nested iterate() function.

graphlog: implement --follow with file arguments

test-glog: test multiple --prune values

graphlog: restore FILE glob expansion on Windows On platforms not supporting shell expansion, scmutil.match() performs glob expansion on 'pats' arguments. But _matchfiles() revset calls match.match() directly, bypassing this behaviour. To avoid duplicating scmutil.match(), a secondary scmutil.matchandpats() is introduced returning both the match object and the expanded inputs. Note the expanded pats are also needed in the fast path, and will be used by --follow code path.

glog: restore multiple --rev test lost in rebasing

copies: remove checkdirs options This removes the undocumented merge.followdirs option, which has always been true.

copies: add docstring for mergecopies

addremove: return 1 if we failed to handle any explicit files
