wait-on-file: don't quote arithmetic argument This is unnecessary and Mac OS X choke on them. Differential Revision: https://phab.mercurial-scm.org/D8425

graft: exit 1 on conflicts, like merge It's more consistent, and makes it nicer to script around hg if you don't have to ignore exit code 255, which is the error code for basically everything in hg. Differential Revision: https://phab.mercurial-scm.org/D8423

tests: deal with "ls" vs "ls -A" difference on 2BSD derived systems BSD-derived systems will use "ls -A" when running as root. Adjust the test cases to always use the flag and include .hg and related output as appropiately. Differential Revision: https://phab.mercurial-scm.org/D8397

tests: skip non-readable check for root Trying to check for errors on non-readable hgrc requires UNIX permissions, but still won't work for root. So adjust the check. Differential Revision: https://phab.mercurial-scm.org/D8396

tests: skip CVS tests for root It is not uncommon for cvs to check for root and to refuse work in that case. Differential Revision: https://phab.mercurial-scm.org/D8395

make: drop the `-c` arg to `install` in the documentation makefile This arg caused `gmake install` on OpenIndiana 2019.10 (illumos) fail with: install: The -c, -f, -n options each require a directory following! install: The -c, -f, -n options each require a directory following! install: The -c, -f, -n options each require a directory following! gmake[1]: *** [Makefile:41: install] Error 2 gmake[1]: Leaving directory '/usr/local/share/mercurial/doc' The workaround is to run `gmake install-bin`. The man page for 10.14 says this is to copy the file and is only for compatability, as it is the default. The CentOS 7 man page says it is ignored. The top level makefile doesn't use this argument at all, so I'm not sure why it's here. Differential Revision: https://phab.mercurial-scm.org/D8439
