File po/GNUmakefile (right):

https://codereview.appspot.com/551830043/diff/573740043/po/GNUmakefile#newcode14
po/GNUmakefile:14: sed-makestuff = -e 's/[a-zA-Z_/]*make\[[0-9]*\].*//'
shouldn't this be rather '[0-9]\+'?

https://codereview.appspot.com/551830043/diff/573740043/po/GNUmakefile#newcode15
po/GNUmakefile:15: sed-edstuff = -e 's/[ \.,adic0-9]*//' -e 's/---//' |
sort -u
I think that within '[...]' you don't have to escape '.'.

And again I would use '\+' instead of '*'.
