run-tests.php esacapeshellarg, portability

hi! While fixing broken tests (linux or win), I found that shell arguments are manually escaped. Using escapeshellargs is more portable and avoid duplicate tests only to fix shell argument issues (& usage for example). Here is a patch to add escapeshellarg usage: http://pierre.libgd.org/patches/runtests_5_3_escapeshellarg.patch.txt A couple of tests need changes, like: inisetting="foo" will become inisetting=foo or inisetting="" to inisetting= Please test the patch or let me know if you have any objection :) Cheers, -- Pierre http://blog.thepimp.net | http://www.libgd.org
