From: Jeff King <peff@xxxxxxxx>
290c8e7a3f (gettext.h: add parentheses around N_ expansion if supported,
2015-01-11) adds a trick for GNU compilers that breaks the build, if an
accidental concatenation of i18n strings is used, but relies on invalid
C that gcc/clang just happen to allow (unless in pedantic mode).
remove that code and all subsequent fixes so that pedantic can run.
an alternative will be provided in a future patch.
