On the other side such trick could probably work as well: "for var in $(cat file); do .... done"

The is not the way to read a file. It sets var to each word in the file, not each line.

or better - use "read".... you might need to play with the FS/IFS settings.

There is no need to play with IFS to read a file line by line.

       o      FBB::indentdec:
              defined in bobcat/indent This manipulator will insert, then reduce the indentation level.

       o      FBB::indentinc:
              defined in bobcat/indent This manipulator will insert, then increment the indentation level.

       o      FBB::lm:
              defined in bobcat/ofoldstreambuf This manipulator sets the left margin of FBB::OFoldStream objects.

       o      FBB::mlm:
              defined in bobcat/ofoldstreambuf This manipulator modifies (alters) the left margin of FBB::OFoldStream objects.

       o      FBB::nlindent:
