 inserts an Author/Modification History block following the first
 "!--" tag in an sqr file.  If the file already contains "! Author"
 or "! Modification History" on the first line following the "!--" tag
 (and is not a blank comment line), an Author/Modification History block
 is not inserted.

 The template for the Author/Modification History block is obtained
 from a file.  The name of the file is obtained by first checking
 the environment variable SQRSH_MODHIST.  If this is not found
 it looks for the environment variable SQRSHDIR and appends the
 name 'modhist.txt'.
