inconsistent comment and code for `all_chars`

[michaelmera]

Comment and code don't agree:

PyGlade/src/glade.py

Lines 183 to 184 in aa5646b

	# List of all printable ASCII characters.
	all_chars = [chr(i) for i in range(128)]

This is not the set of printable ASCII characters but all ASCII characters. I don't know what the intent was, but you should fix either the code or the comment.

Note also that the string module in the standard library provides the constant printable for the set of printable characters.

The comment shall be changed to be "List of all ASCII characters."
