If you don't want to deal with the branch approach suggested by the
other Joshua you could (ab)use the clean&smudge filters (see "filter" in
gitattributes(5)):

Define a clean filter such as "fgrep -v GITIGNORE" and mark every source
line which you want to ignore with a comment:

printf("Happy we got this far but I have no clue why"); // GITIGNORE

You can do more clever things with awk or sed, of course. "GITIGNORE" is
just some hopefully unused string.

Note that a "checkout" would overwrite your debug lines!
