Revision f3cad0ad82e24966bf7bcc8a47670c54c30e4b18 authored by Johannes Sixt on 07 February 2009, 15:08:28 UTC, committed by Junio C Hamano on 07 February 2009, 20:23:29 UTC 
Move sanitary_path_copy() to path.c and rename it to normalize_path_copy()
 
This function and normalize_absolute_path() do almost the same thing. The
former already works on Windows, but the latter crashes.

In subsequent changes we will remove normalize_absolute_path(). Here we
make the replacement function reusable. On the way we rename it to reflect
that it does some path normalization. Apart from that this is only moving
around code.
