// ReMatchMsg - match regular expression against the message directly.
//
// This class is derived from ReMatch, and is used when a regular expression
// should be matched against the message directly.
// It defines the virtual functions from ReMatch to go against the Message
// class itself.
//
// The constructor takes two flags: headeronly, and mergelines.
// "headeronly" forces and end-of-file condition when a blank line is found
// in the message. "mergelines" causes a newline character to be silently
// eaten, when it is immediately followed by a space. The flags must be
// set as follows, in the following situations:
//
// A) Match header and body: mergelines is true, headeronly is false
// B) Match header only: mergelines is true, headeronly is true
// C) Match body only: mergelines is false, headeronly is false,
// also the message must be seeked to the
// start of the message contents.
//
