Issue a warning if "-r ." is used with two working directory parents.
Rationale for not aborting instead:
The first parent is usually more important as it is the local branch
during a merge and commands like 'hg diff' and 'hg diff -r.' behave still
identically (except for the warning of course).
Added a test for log -r. with one and two parents.
adding bar
adding foo
adding bomb
adding a.c
adding dir/a.o
adding dir/b.o
M dir/b.o
! a.c
! dir/a.o
? .hgignore
a.c: unsupported file type (type is fifo)
! a.c
# test absolute path through symlink outside repo
A f
# try symlink outside repo to file inside
abort: ../z not under root
# try cloning symlink in a subdir
1. commit a symlink
? a/b/c/demo
adding a/b/c/demo
