Checking subset and removing extra letters
In each line of file, I wish to check if word1 is a non-connected subset of any of the other words in the line. If yes, keep only the words that ward1 is a subset of. Else, remove the whole line.
Also, I want to remove the letters that word1 doesn't match with, except for "_+"

Example file:
Code:
abcde  abc_+hde   ab_+ce_+de
higk    h_+al_+gk 
xyz     a_+xyz      axy_+s

Desired output:
Code:
abcde  abc_+de     ab_+c_+de
xyz     xyz

NAME

       stl_image - Software subset image data files

DESCRIPTION

       Each  software  product that is distributed as subsets for the setld(8) command has an associated image data file.  This image data file is
       created by the kits(1) utility.	The image data file's name consists of the product's unique 3-letter name with the  string  .image  for  a
       suffix.	The image data file contains one record for each subset in the kit.  Each record contains three fields separated by white space:

       Checksum     The modulo-65536 checksum of the subset file (after compression, if the file is compressed)

       Size	    The size of the subset file in kilobytes (after compression, if the file is compressed)

       Subset name  The product code, subset mnemonic, and version number

EXAMPLES

       The following example illustrates OAT.image, the image data file for a hypothetical kit: 15923	 70 OATDCB100 24305   400 OATDCBDOC100

RELATED INFORMATION

       Commands:  gendisk(1), gentapes(1), kits(1), setld(8)
