my previous commit in this function added a block that happened
to follow directly after a bodiless while loop, i.e. 'while(...);'.
clang spotted this and warned. So add an empty body '{}' after the
while to visually disambiguate it.
case FF_NEWLINE: /* delete trailing spaces, then append \n */
f++;
- while (t-- > (SvPVX(PL_formtarget) + linemark) && *t == ' ') ;
+ while (t-- > (SvPVX(PL_formtarget) + linemark) && *t == ' ')
+ {}

{
STRLEN cur = t - SvPVX_const(PL_formtarget);
t = SvGROW(PL_formtarget, cur + 1 + 1) + cur;
