Change `while(<$fh>) { my $c = $_' to `while(my $c = <$fh>) {', and
use `chomp $c' instead of `$c =~ s/\n$//g;', the two are equivalent in
this case.
I've also changed the --cccmd test so that we test for the stripping
of whitespace at the beginning of the lines returned from the
--cccmd. I think we probably shouldn't do this, but it was there
already so I haven't changed the behavior.

Change the use of Sys::Hostname from a "use" to a "require". The
former happens in an implicit BEGIN block and is thus immune from the
if block it's contained in, so it's always loaded.

The code had several places where individual checks were done to remove
files that could be in the way of directories in D/F conflicts. Not all
D/F conflicts could have a path cleared for them in such a manner, however,
leading to the need to create make_room_for_directories_of_df_conflicts()
as done in the previous patch. That new function could not have been
incorporated into the code sooner, since not all relevant code paths had
been deferred to process_df_entry() yet, leading to the creation of even
more of these now-redundant path removals.

When a commit moves A to B while another commit created B (or moved C to
B), and these two different commits serve as different merge-bases for a
later merge, c94736a (merge-recursive: don't segfault while handling
rename clashes 2009-07-30) added some special code to avoid segfaults.
Since that commit, the two versions of B are merged in place (which could
be potentially conflicting) and the intermediate result is used as the
virtual ancestor.
However, right before this special merge, try_merge was turned on, meaning
that process_renames() would try an alternative merge that ignores the
'add' part of the conflict, and, if the merge is clean, store that as the
new virtual ancestor. This could cause incorrect merging of criss-cross
merges; it would typically result in just recording a slightly confusing
merge base, but in some cases it could cause silent acceptance of one side
of a merge as the final resolution when a conflict should have been
flagged.
When we do a special merge for such a rename/add conflict between
merge-bases, turn try_merge off to avoid an inappropriate second merge.

process_renames() and process_entry() have nearly identical code for
doing three-way file merging to resolve content changes. Since we are
already deferring some of the current rename handling in order to better
handle D/F conflicts, it seems to make sense to defer content merging as
well and remove the (nearly) duplicated code sections for handling this
merging.
To facilitate this process, add a new update_stages_and_entry() function
which will map the higher stage index entries from two files involved in a
rename into the resulting rename destination's index entries, and update
the associated stage_data structure.

information about the rename needed at D/F resolution time, and then make
use of that information when resolving D/F conflicts at the end.

If merging two lines of development involves a rename/add conflict, and two
different people make such a merge but resolve it differently, and then
someone tries to merge the resulting two merges, then they should clearly
get a conflict due to the different resolutions from the previous
