Subject: use strbuf_add_unique_abbrev() for adding short hashes
X-Git-Tag: v2.9.4~7^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/1eb47f167d65d1d305b9c196a1bb40eb96117cb1?hp=1eb47f167d65d1d305b9c196a1bb40eb96117cb1

use strbuf_add_unique_abbrev() for adding short hashes

Call strbuf_add_unique_abbrev() to add abbreviated hashes to strbufs
instead of taking detours through find_unique_abbrev() and its static
buffer.  This is shorter and a bit more efficient.
