Revision 33ad9ddd0b5398063f0aabea639b5fe569f458ea authored by René Scharfe on 25 February 2017, 16:00:33 UTC, committed by Junio C Hamano on 27 February 2017, 19:02:06 UTC 
strbuf: add strbuf_add_real_path()
 
Add a function for appending the canonized absolute pathname of a given
path to a strbuf.  It keeps the existing contents intact, as expected of
a function of the strbuf_add() family, while avoiding copying the result
if the given strbuf is empty.  It's more consistent with the rest of the
strbuf API than strbuf_realpath(), which it's wrapping.

Also add a semantic patch demonstrating its intended usage and apply it
to the current tree.  Using strbuf_add_real_path() instead of calling
strbuf_addstr() and real_path() avoids an extra copy to a static buffer.
