[PATCH] describe: use strbuf_add_unique_abbrev() for adding short hashes

["René Scharfe" <l.s.r@web.de>]

Call strbuf_add_unique_abbrev() to add an abbreviated hash to a strbuf
instead of taking a detour through find_unique_abbrev() and its static
buffer.  This is shorter and a bit more efficient.

Patch generated by Coccinelle (and contrib/coccinelle/strbuf.cocci).
