We may take the path to a bundle file as an argument, and
need to adjust the filename based on the prefix we
discovered while setting up the git directory. We do so
manually into a fixed-size buffer, but using
prefix_filename() is the normal way.
Besides being more concise, there are two subtle
improvements:
1. The original inserted a "/" between the two paths, even
though the "prefix" argument always has the "/"
appended. That means that:
cd subdir && git bundle verify ../foo.bundle
was looking at (and reporting) subdir//../foo.bundle.
Harmless, but ugly. Using prefix_filename() gets this
right.
2. The original checked for an absolute path by looking
for a leading '/'. It should have been using
is_absolute_path(), which also covers more cases on
Windows (backslashes and dos drive prefixes).
But it's easier still to just pass the name to
prefix_filename(), which handles this case
automatically.
Note that we'll just leak the resulting buffer in the name
of simplicity, since it needs to last through the duration
of the program anyway.
