Syntactic relaxation: Allow /# and #/ to be indented

[Chuck]

In a text editor that maintains indentation when you press ENTER, it is annoying to have to BACKSPACE or HOME to type /#

Also, there is no known advantage to /# and #/ being required at the beginning of the line.

Do not allow tabs and spaces to be mixed prior to the /# or #/.

And there is no requirement that the /# and #/ be aligned with each other.

patch + test+ relnote.

Its possible to remove the ambiguous comment error message/handling entirely
( in favour of block comment)
by tweaking patch above.

			r'INLINE_COMMENT	\/\#.*\#/',
-			r'COMMENT_BLOCK_START	^\/\#.*$', 
+			r'COMMENT_BLOCK_START	\/\#.*$', 
			r'SINGLE_LINE_COMMENT	\#.*',
-			r'AMBIGUOUS_COMMENT	\/\#.*',

and removing CobraTokenizer refs to AMBIGUOUS_COMMENT and
Tests/110-basic/160-lines-and-comments/302-inline-comment-error.cobra

Patch applied in changeset:2040. Thanks.

I'm leaving the ambiguous comment error for now. We can relax that restriction later, if need be.
