           Summary: regexp mapper substitution doesn't work properly
           Product: Swift
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: General
        AssignedTo: hategan at mcs.anl.gov
        ReportedBy: hategan at mcs.anl.gov


The following produces an error:
...
countfile c<regexp_mapper;source=@inputfile,match="(.*)in",transform="\1out">;
...

Namely: Could not compile SwiftScript source: line x:72: unexpected char: '1'

This is probably introduced by the "\" escaping scheme added at some point.

Using countfile 
...
c<regexp_mapper;source=@inputfile,match="(.*)in",transform="\\1out">;
...

does not produce an error, but the transformed name has a backslash prefixed.
