This simple CLI utility converts RSV (Rows of String Values) files to human readable format.
RSV is a schemeless text-based data transport format, very similar to CSV, but with binary separator characters, so there's no quotation marks, no escaping at all. Easy to create, easy to read, payload can be any UTF-8 character.
For more info and examples, see the specification.
If any files are specified,
the program concatenates them,
if not, it uses stdin (piping support).

The empty string ('') is unnecessary,
but it's easier to understand.

There's no such as final version of a software.
Now, this utility omits all CR characters, and takes LFs as end-of-line. Probably, this is a bad behaviour, these characters may appear in the payload.
Solution: add command line switch to interpret CR and LF characters as data.
Now the program prints LF after each line, regardless of line ending parameter's value.
Solution: make it switchable.
Delimiter characters
should be read
from a user preference file,
e.g. ~/.rsvw-rc.
