[creduce-bugs] Shortening line bug in c-reduce

[Tzafrir Poupko <tzafrir11@gmail.com>]

Hi All,

I'm reducing non pre-processed files, and notice the following 'funny' bug.

In the project I'm reducing, there is a include file

#include "folderA/folderb.h"

which includes all the files in folder b, so the content is for example

#nclude "folderA/folderb/file1.cpp"
#include "folderA/folderb/file2.cpp"
#include "folderA/folderb/file3.cpp"

After running creduce on the source and the headers, it turns out my code only depends on
#include "folderA/folderb/file3.cpp"

If I now run creduce and let it perform all the passes, one of the passes deletes single characters from a line

changing this include line to

#include "folderA/folderb.cpp"

And actually throws me back in the reduce process.

Maybe this pass can check and not shorten include lines?
