To discover filenames from the --- and +++ lines in a traditional unified diff, currently "git apply" scans forward for a whitespace character on each line and stops there. It can't use the whole line because "diff -u" likes to include timestamps, like so: --- foo 2000-07-12 16:56:50.020000414 -0500 +++ bar 2010-07-12 16:56:50.020000414 -0500 The whitespace-seeking heuristic works great, even when the tab has been converted to spaces by some email + copy-and-paste related corruption. Except for one problem: if the filename itself contains whitespace, the inferred filename will be too short. When Giuseppe ran into this problem, it was for a file creation patch (for debian/licenses/LICENSE.global BSD-style Chromium). So one can't use the list of files present in the index to deduce an appropriate filename (not to mention that way lies madness; see v0.99~402, 2005-05-31). Instead, look for a timestamp and use that if present to mark the end of the filename. If no timestamp is present, the old heuristic is used, with one exception: the space character \040 is not considered terminating whitespace any more unless it is followed by a timestamp.
