Changes since 1.12: +29 -35 lines

Fix quoting (quotes really do not nest...) and remove a bunch of it
that is harmless, but also pointless (in sh, quotes do not make strings,
everything is a string, rather they hide characters which would have
some other meaning unquoted (like spaces) - quotes are not needed around
strings like "descr" so remove them...

Be more consistent with line wrap style, try to avoid wrapping in the
middle of a (sh) word where possible.   Avoid \ use when it is not needed.

Un-KNF (C style) - sh has no declarations, there is no need to leave
blank lines at the head of a function to mark the end of the declarations.

This should be a NFC - but the quoting really was broken before, just
was probably harmless breakage.
