While working on PR117028 C2Y changes, I've noticed weird ternary
operator formatting (operand1 ? operand2: operand3).
The usual formatting is operand1 ? operand2 : operand3
where we have around 18000+ cases of that (counting only what fits
on one line) and
indent -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2 -ndj \
       -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob
documented in
https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting
does the same.
Some code was even trying to save space as much as possible and used
operand1?operand2:operand3 or
operand1 ? operand2:operand3

Today I've grepped for such cases (the grep was '?.*[^ ]:' and I had to
skim through various false positives with that where the : matched e.g.
stuff inside of strings, or *.md pattern macros or :: scope) and the
following patch is a fix for what I found.
