[Bug-indent] C++ ability for indent .. code patch and question.

[Preston A. Elder]

Hi,

I use indent on C++ code, works fine, however, as stated in the docs, I 
end up with the template problem of:
a< b< c>>;

I found the fix was to modify lexi.c, and insert the following code at 
line 1020 (ie. the detection code for the lexical token of '<', '>' and 
'!'):
            if (token - cur_line)
                if (token[-1] == ' ' || token[-1] == TAB)
                    parser_state_tos->want_blank = true;

This should force the parser to maintain a space before a <, > or ! 
character if there was one there already.  I cannot see any ill effect 
from this code, and the only changes I've noticed in my code (after 
doing comparisons between a standard indent, and the one modified with 
the above code), is that the template problem is fixed.  This was tested 
on rather complex code, in a file that is 426kb.

If you can think of any reason why this is NOT a good idea, I'm all 
ears.  The only thing I dont like about this, is I've had to use the 
cur_line veriable outside the io.c file (which is the only place it is 
used currently), but I dont know how else to check if the token string 
is starting at the beginning of the line or not (last thing we want is 
to do blow our boundaries!).

BTW - I love the program, and it works well, and has alot of cool 
options -- for all my (and others) formatting needs.  Good job :)
