[PATCH] Fix make_absolute_path() for parameters without a slash

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

When passing "xyz" to make_absolute_path(), make_absolute_path()
erroneously tried to chdir("xyz"), and then append "/xyz".  Instead,
skip the chdir() completely when no slash was found.

	I should add a test, but I am simply too tired now.  Will do so 
	tomorrow.
