[PATCH] Remove tab character from conflicted files list part of the merge message

[Andy Parkins <andyparkins@gmail.com>]

Merge can generate sections like this:
 Conflicts:
   file1
   file2
   file3
The filenames were moved forward by embedding a tab.  Tabs are variable
width, so there is no guarantee that the appearance would be the same on
different systems.  In this case the tabs are being used for formatting,
for formatting, spaces are better.

This patch simply swaps the tab for four spaces in the "Conflicts:"
section.

The reason this makes a difference (to me), is that I often edit the
conflict section to say what the resolution of the conflict was,  I
happen to have expandtabs set for git log messages (to guarantee they
look the same regardless of the viewer's settings), and hadn't noticed
that git was putting tabs into the log message for me.

So what I thought I was formatting as (for example)

Conflicts:
    file.c
     * Chose upstream version over mine, but integrated my small typo fix.

Was appearing in the log display as

Conflicts:
        file.c
     * Chose upstream version over mine, but integrated my small typo fix.

Which isn't how I'd intended at all.

The fix is of course - no tabs.  Tabs for formatting is always going to cause
trouble, so this patch swaps the tab for spaces.

I don't think the actual number of spaces is important (I chose 4), as long
as there are no tab-surprises in the log message (unless the user put them
there themselves of course - but that's their own fault).
