[Cocci] Determining the second line indent amount?

[Cocci] Determining the second line indent amount?

[Timur Tabi]

I want to write a Python script that will word-wrap long literal
strings.  In order to do that properly, I need to know how many spaces
the parameter is indented, so that I can guarantee that the string is
wrapped at column 80.  Is that information available?

Coccinelle puts long strings on their own line (in my case, it's
always the second parameter), so I think all I will need is the indent
amount that Coccinelle uses for multi-line function calls, not any
specific parameter.

You only have access to the number of characters from the beginning of the
line (col field of a position variable), but you don't know whether those
characters are spaces or tabs.  If your software only uses spaces, then
the number would be reliable.
