If a comment in an INSTALL file contains the name of a valid INSTALL file function but the function itself is not present, pacman tries to execute that function. That leads to an error.
Ignore comments in the grep function in libalpm/trans.c to avoid such erros.

This is fine. We really need to improve this area to do better than a grep...
Puled to my patchqueue with typo in commit message fixed.
