Changed the ptouch bash function to use the "Text Last Updated"
date reported by 'svn info' when changing the modified time
(mtime) of the file/symlink/directory in the git working
directory.  Previously it used the mtime of the item in the
svn working directory, which caused the race condition.

[ew: swapped argument order of ptouch() to minimize diff]
