[PATCH] maint: enforce one small aspect of formatting style: space-before-"(" |

FYI, I've just pushed this to coreutils.
Note that I've embedded both a default exemption regexp,
as well as the one I'm using in coreutils.
Obviously only the default would go into gnulib's maint.mk
Eric suggested that I put this in gnulib's maint.mk.
This is a pretty fundamental axiom of formatting in gnu projects,
so I suspect few would object outright, especially since it's
such an easy matter to conform or to disable the check:
To disable, add to the "local-checks-to-skip" definition
you probably already have in cfg.mk:
local-checks-to-skip += sc_space_before_open_paren
Any objections?
An alternative, if this is deemed too invasive,
[In any project of nontrivial size, the exemption regexp will
have to be derived if this check is not turned off. ]
is to create a new class of syntax checks:
ones that are provided, but that are turned off by default,
and put this test in that new category.
