Fixed some issues with multiline comments in pass-thru mode

[p2k]

(Getting to the point straight away:)

Sample input 1:

/*
multiline
comment
*/

void shouldBeOnLineSeven();

Output of $ pcpp --passthru-comments test1.h before patch:

/*
multiline
comment
*/

void shouldBeOnLineSeven();

Sample input 2:

/*
a
comment
that
spans
eight
lines
*/

void shouldBeOnLineEleven();

Output of $ pcpp --passthru-comments test2.h before patch:

/*
a
comment
that
spans
eight
lines
*/
#line 11 "test2.h"
void shouldBeOnLineEleven();

After patching, it correctly outputs the same output as the respective input. While the result of the second example is non-fatal, the first example shifts the line numbers illegally.

The fix addresses the problem with a rather simple trick of adjusting the last line number while iterating over the final token list. I also took the liberty of removing the blankacc list that wasn't used.

Many thanks for the bug report. I've got the unit tests correctly failing with your sample inputs. I'll look into the bug fix tomorrow night.

I rewrote it and did a bit more refactoring. Thanks for the bug report and fix!
