From the PR:

	The PCCard daemon can hang indefinately while reading its
	configuration file. If the last line of the file is a comment line
	that does not end in a newline, the program goes into an infinite
	loop searching for the non-existent newline.

This fix, provided by the PR, will allow files ending without a newline
to be read without hanging.
