.IX Subsection "CLASS->safe_quote ITEM"
Quotes an item to become safe against spaces
in shell interpolation. An item is enclosed
in double quotes if:
.PP
.Vb 2
\& \- the item contains spaces in the middle
\& \- the item does not start with a quote
.Ve
.PP
This happens to avoid shell interpolation
problems when whitespace is present in
directory names.
.PP
This method uses \f(CW\*(C`commands_quote\*(C'\fR to determine
the correct quote. If \f(CW\*(C`commands_quote\*(C'\fR is
a space, no quoting will take place.
.PP
if it starts and ends with the same quote character: leave it as it is
.PP
if it contains no whitespace: leave it as it is
.PP
if it contains whitespace, then
.PP
if it contains quotes: better leave it as it is
.PP
else: quote it with the correct quote type for the box we're on
