Q:

Bash here docs <<- skipping leading blanks

I can do this:
declare foo -r -d '' <<- 'EOF'
->-> Sopra la panca
->-> la capra campa
EOF

(where -> represents a TAB)
The leading tabs will then be ignored.
Can <<- be used to skip/ignore leading spaces, not just tabs? 

A:

To quote
from Greg

In this form, all leading tab characters (not spaces!) will be removed. There is 
no provision for removing leading spaces, or leading tabs-and-spaces. (Recall the
syntactic restrictions of Makefiles, and you'll be OK.)
