[Libguestfs] [PATCH 0/4] Replace some uses of the Str module with PCRE.

Str is a pretty ugly regexp module. Let's try to replace it with PCRE. This series of commits goes some small way towards that eventual goal. - - - I wonder if there was a deep reason why we had this? let unix2dos s = String.concat "\r\n" (Str.split_delim (Str.regexp_string "\n") s) I replaced it with what I think should be (nearly) equivalent: let unix2dos s = String.concat "\r\n" (String.nsplit "\n" s) Rich.
