* maintainers/scripts/rebuild-amount.sh: report parallelism setting
This slightly helps discovering parallelism support.
* maintainers/scripts/rebuild-amount.sh: add basic example
It's not clear if script should be used against HEAD or HEAD^.
Let's have a copyable example.
* maintainers/scripts/rebuild-amount.sh: convert tabs to four spaces
One notable change is here-document conversion.
Before:
<TAB>cat <<-FOO
<TAB>...
<TAB>FOO
After:
<sp><sp><sp><sp>cat <<FOO
<sp><sp><sp><sp>...
FOO
Note seemingly misaligned 'FOO': '-FOO' understands leading tabs,
but not spaces.
