1) Commandline options must have priority
2) Only safe options (-Z, -p, -z) permitted for using from patchfile by 
default. Other options may be ignored or special policy may be applied for they.

For public patches only -Z is need at this time. But for internal usage any 
options may be passed through this mechanism.

Unification. If options as -Z (non dangerous but critical in some situations) 
will be added, we
don't have to rebuild diff/patch for passing it via patchfile.
