In the interest of code hygiene, make it easier to compile Git with the flag -pedantic. Pure pedantic compilation results in one warning per use of the translation macro `N_`, therefore also disable the parenthesising of i18n strings with -DUSE_PARENS_AROUND_GETTEXT_N=0 to show only real warnings.
I like this...
quoted hunk ↗ jump to hunk
diff --git a/Makefile b/Makefile index 0cb6590f24..f800054379 100644 --- a/Makefile +++ b/Makefile@@ -484,6 +484,10 @@ all:: # The DEVELOPER mode enables -Wextra with a few exceptions.

But let's mention that we toggle USE_PARENS_AROUND_GETTEXT_N implicitly when this is set here.
quoted hunk ↗ jump to hunk
+CFLAGS += -pedantic +# don't warn for each N_ use +CFLAGS += -DUSE_PARENS_AROUND_GETTEXT_N=0 +endif
...and set this to "no" not "0" since we document that that's the way to
toggle it off in the Makefile, i.e. let's be consistent.
Also, it would be helpful for future digging if the commit message
mentioned which -W flag included in -Wpedantic is triggering this
USE_PARENS_AROUND_GETTEXT_N condition that previously wasn't triggered,
and on which compiler & version. 290c8e7a3f ("gettext.h: add parentheses
around N_ expansion if supported", 2015-01-11) doesn't mention anything
like that.
