The indentNextLine increase the indent relative to the current indent level.
This is kept in a register which is preserved if next line is also matched by the indentNextLine pattern.
An example where this makes sense would be:
for(size_t i = 0; i < 10; ++i)
I don’t think TextMate 1.x is able to properly indent the above, but 2.0 will, even while you type it.
The downside of the line-based rule system is that breaking one statement across multiple lines is effectively unsupported, since each fragment is matched against the patterns and will thus be wrongly classified. I don’t know how this can be improved (other than do binary parsers for each language, but even that is quite a challenge for languages like C++).
