The current error handling for the multiline variable parser is a bit fragile, as each error condition has its own code to clear memory. Instead, unify error handling as far as possible to avoid this repetitive code. While at it, make use of `GITERR_CHECK_ALLOC` to correctly handle OOM situations and verify that the buffer we print into does not run out of memory either.

I've amended this PR to improve the error handling of this function in general. It's much too frickle in my opinion. Please let me know if you're fine with those changes |
