Hi,

As someone pointed out, I did not fix all the corner cases with 
linespec_lexer_lex_number.  [See 
http://sourceware.org/ml/gdb/2012-07/msg00078.html - the issue affects 
all platforms]

Since it is still quite common for MI-based UIs to quote the entire 
linespec, we need to terminate numbers successfully on any quotation.

While the list of growing terminations for the string is getting 
tediously long, I don't think inverting the test would be any 
shorter/clearer. WDYT?

Keith

PS. Also recommending this for 7.5.

	* linespec.c (linespec_lex_number): A number followed
	by quotes is a valid number, too.
