[RFA] linespec.c change to stop "malformed template specification" error

[Daniel Berlin <dan@cgsoftware.com>]

This error is cause by find_toplevel_char not knowing that '<' and '>'
increase and decrease the depth we are at.

The result is that if you say "break _Rb_tree<int, int>", when it goes
to look for a comma at the top level, it thinks it found one right
after the "int", and temporarily truncates the string to '_Rb_tree<int,'
When we then proceed to go through the string, we see the "<", and
then go to find the end of the template name, and can't, because we've
truncated the string in the wrong place, and issue an error.

Cute, no?

 	* linespec.c (find_toplevel_char): '<' and '>' also increase and
 	decrease the depth we are at, in the case of templates.
