Likely bug in add_multi_line.

[1uc]

It would seem that from the second line onward, under-indented code will be printed incorrectly. For example:

add_mutli_line(R"(
     x;
fooo;kkk
)");

would likely produce:

{indent}x;
{indent}kkk

The likely culprit is:

nmodl/src/printer/code_printer.cpp

Line 86 in 38f90ff

add_line(line.substr(prefix_length));

because it only considers the first line for guessing the indentation level of the multi-line string.

(I've not 100% confirmed it's bugged.)
