Before sha1_to_hex_r() existed, a simple way to get hex sha1 into a buffer was with: strcpy(buf, sha1_to_hex(sha1)); This isn't wrong (assuming the buf is 41 characters), but it makes auditing the code base for bad strcpy() calls harder, as these become false positives. Let's convert them to sha1_to_hex_r(), and likewise for some calls to find_unique_abbrev(). While we're here, we'll double-check that all of the buffers are correctly sized, and use the more obvious GIT_SHA1_HEXSZ constant.
