Subject: [PATCH 1/3] Mergetool generating blank files (1.5.3)

When mergetool is run from a subdirectory, "ls-files -u" nicely
limits the output to conflicted files in that directory, but
we need to give the full path to cat-file plumbing to grab the
contents of stages.

Subject: [PATCH 2/3] mergetool: fix emerge when running in a subdirectory

Only pass the basename of the output filename when to emerge, since
emerge interprets non-absolute pathnames relative to the containing
directory of the output buffer.

Thanks to Kelvie Wong for pointing this out.
