[PATCH 0/3] builtin-branch: use strbuf

These 3 patches do what's in the subject: use the strbuf API instead of
snprintf() / sprintf().

The current risk of writing unallocated memory is low, I think, but
still, the return value of these functions were not checked at several
places.

Miklos Vajna (3):
  builtin-branch: use strbuf in delete_branches()
  builtin-branch: use strbuf in fill_tracking_info()
  builtin-branch: use strbuf in rename_branch()
