[Bug-indent] Re: indent bug with formatting in " "

[David Ingamells]

Mike,
I have just taken over as the maintainer of indent.

There seem to be several reports of the error you encountered so it seems a 
good place for me to start. I will produce a solution for this, but I 
recommend that you follow the suggestion that Carlo made with one important
modification, namely that each line in the string should end with \n, e.g.

char *format = "%c %c %c\n"
                        "%c %c %c\n"
                         "%c %c %c\n";

This works with ANSI C compilers because the ANSI standard says that two
consecutive strings separated only by white space should be joined into one 
string. Thus the above statement is equivalent to 

char *format = "%c %c %c\n%c %c %c\n%c %c %c\n";

I recommend this because:

1) the code layout is much cleaner.
2) there are no hidden control characters (e.g. the newline) in the string.

Please note the new mail address for posting bugs (or comments, suggestions, 
etc.)

I'll let you know when I have a new release, just bear with me while I find 
my way around the code.

Regards,

David Ingamells.
