largefiles: report the missing file count after a commit that does nothing This is the same warning that is printed for normal files.

commit: factor the post commit status check into a cmdutil method The largefiles extension needs to set lfstatus for this status call. Otherwise, if a missing largefile is explicitly named, a confusing message is issued that says the largefile wasn't found, followed by another that says nothing changed.

largefiles: fix an explicit largefile commit after a remove (issue4969) The change in b68797f244e4 to handle a normal -> largefile switch was too aggressive in preserving the original matcher names. If a largefile is explicitly provided by the user, but only the standin exists in dirstate, then only the standin can be committed. There's still maybe an issue when the largefile is deleted outside of Mercurial: $ rm large $ hg ci -m "oops" large large: The system cannot find the file specified nothing changed [1]
