Remove trailing whitespace in printf

The only tricky ones were
Assembleur/src/gdb.c
C/S3-src/strcat.c
because they output something like
1 2 3
with
for(i=0;i<n;i++) {printf("%d ",i);} printf("\n");
What I commonly do in that case is
for(i=0;i<n;i++) {printf("%d%c",i,(i+1==n)?'\n':' ');}
but that can be considered as tricky for LSINF1252 so I've written
for(i=0;i<n;i++) {printf(" %d",i);} printf("\n");
which outputs
 1 2 3
