'Match' attempts to find a match for a regular expression
anywhere in a given line of text.
The first argument contains the text line;
the second contains the pattern to be matched.
The function return is YES if the pattern was found anywhere in
the line, NO otherwise.
.sp
The pattern in 'pat' is a standard Subsystem encoded regular
expression.
'Pat' can be generated most conveniently by a call to the routine
'makpat'.
.im
'Match' calls 'amatch' at each position in 'lin', returning
YES whenever 'amatch' indicates it found a match.
If the test fails at all positions, 'match' returns NO.
