This is some awk code. Because you wanted to add days to lines where it could not be calculated, this code is two awk scripts in one bash script. It could be cleaned up.
It adds -1 to lines in error, error being a singleton line.
Code:
$ cat filename && ./t.awk

rmdel

sccs-rmdel(1)							   User Commands						     sccs-rmdel(1)

NAME

       sccs-rmdel, rmdel - remove a delta from an SCCS file

SYNOPSIS

       rmdel -rsid s.filename...

DESCRIPTION

       The  rmdel utility removes the delta specified by the SCCS delta ID (SID) supplied with -r. The delta to be removed must be the most recent
       (leaf) delta in its branch. In addition, the SID must not be that of a version checked out for editing: it must not appear in any entry	of
       the version lock file (p.file).

       If you created the delta, or, if you own the file and directory and have write permission, you can remove it with rmdel.

       If  a  directory  name  is used in place of the s.filename argument, the rmdel command applies to all s.files in that directory. Unreadable
       s.files produce an error; processing continues with the next file (if any). The use of `-' as the s.filename argument  indicates  that  the
       names of files are to be read from the standard input, one s.file per line.

OPTIONS

       The following option is supported:

       -rsid	Remove the version corresponding to the indicated SID (delta).

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of rmdel: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

FILES

       p.file	 permissions file

       s.file	 history file

       z.file	 temporary copy of the s.file

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
