I think this requires a config variable:
- The indentation you show above is the one that makes sense to me,
where the \ is just a way to write "a b" on multiple logical lines,
like you can do in most free-form programming languages, in which case
"b", being an argument to "a", should be indented a bit deeper than
"a". I.e. the indentation rule pretends the \ don't really exist.
- The indentation you ask for seems to be based on the idea that "\" is
a way to split a single logical line into several physical lines,
doing a kind of manual "word wrap".
IOW the first view would want
for f in a; do \
for g in b; do \
echo toto; \
done; \
done
[ tho I see now that the current code fails here (probably because it
doesn't understand that the "do"s are "hanging"). ]
whereas the second view would want
for f in a; do \
for g in b; do \
echo toto; \
done; \
done
I don't see a way to reconcile those two views, hence the need for
a config variable to choose between those two schools.
