libguestfs/generator/php.ml
Richard W.M. Jones 02b64d5cec generator: Use quoted string literals in many places 
This change was done almost entirely automatically using the script
below.  This uses the OCaml lexer to read the source files and extract
the strings and locations.  Strings which are "candidates" (in this
case, longer than 3 lines) are replaced in the output with quoted
string literals.

Since the OCaml lexer is used, it already substitutes all escape
sequences correctly.  I diffed the output of the generator and it is
identical after this change, except for UUIDs, which change because of
how Utils.stable_uuid is implemented.

Thanks: Nicolas Ojeda Bar
