log-tree: fix patch filename computation in "git format-patch"
When using "git format-patch", "get_patch_filename" in
"log-tree.c" calls "strbuf_splice" that could die with
the following message:
"`pos + len' is too far after the end of the buffer"
if you have:
buf->len < start_len + FORMAT_PATCH_NAME_MAX
but:
buf->len + suffix_len > start_len + FORMAT_PATCH_NAME_MAX
This patch tries to get rid of that bug.
[jc: w/ simplified logic]
