// strpatch.h  - patch to the <string> template

/* The revised getline function is a variation on getline,
specifically for reading from the Win95 console. It
prevents the user from having to press Enter twice 
to end the input. Format:

istream & getline( istream &, const string &, char delim,
          bool isConsole );
